Packing list
This list takes inspiration and humbly gives credit to the original source Scott's Firefly Packing List
Critical
Your photo ID - You will not get in to Firefly without your ID. It is your ticket.
Shelter
Tent - When purchasing a tent make sure it has a rain cover. There are a large variety of vendors for tents, so check reviews on their durability. Be mindful of your fellow fireflies and purchase a reasonably sized tent for the number of people who will be sleeping in the tent.
Bedroll - Having some kind of pad underneath your sleeping bag is highly recommended. Not all camp locations will have even ground, and this layer of padding will help you sleep comfortably. This can be anything from camping-specific pads up to full air mattresses. Don't forget to bring a patch kit just in case.
Sleeping bag - Average lows for New Hampshire in July are in the low 50's, so there is a small chance that the temperature could be in the 40's for a short time overnight. However, it could also stay in the 70's. You likely wont need a heavy-duty sleeping bag for Firefly but you should at least be prepared for chilly nights.
Pillow - Its where your head goes and most find it tough to sleep without one.
Tarp - While not required, having an extra tarp and a means to stand it up, either by string to trees or tarp poles can help if rain occurs for an extended period of time.
Rope - Cheap and widely useful
Towel - Widely useful in a well-documented set of circumstances
Clothing
Warm top and bottom - While it may not happen, temperatures could get down into the low 50's at night.
Waterproof rain gear - The likelihood of rain at some point during a summer week in New England is near 100%. Rain ponchos, or jackets and pants will help to keep you dry
Extra socks and underwear - Takes up little space but provides amazing relief if it rains
Sturdy footwear - Boots are a strong recommendation as the grounds are essentially hilly hiking trails. You will likely be walking more during firefly than you do normally. During load-in, and load-out especially, a good pair of boots will protect your ankles. The walk from the drop-off and porta-potty area is at least 10 minutes depending on the location of your camp.
Eating and Hydration
Provisions - Enough food and water for each person in your party for the week.
Cup - Durable and re-usable, fireflies often have drinks to sample as you walk around and are happy to fill yours up.
Water container - When camping you'll be losing more water than normal, so keeping up with your hydration is critical.
Backup water - Water is available on site but you should practice self-reliance and bring at least a two gallon container of water per person. At best aim for 1 gallon of water per person per day of camping.
Fork, spoon, knife - Gets food in your face. Reusable, to keep waste low.
Carry pack - Bag or belt, something to hold things while you walk around. Unfortunately, we only have at most two hands and they fill up pretty quick.
Headlamp - With red-mode preferred. Notice how taillights on cars are red while headlights are white? White light can shrink pupils in the dark where red light does not, so be kind to your fellow fireflies and avoid temporarily blinding them in the dark.
Earplugs - The loud areas of the event are quite loud well into the night. Both to protect your ears, and to help you sleep, earplugs are strongly recommended.
Trash bags - You will generate some waste during the event, or you may find Material Out Of Place (MOOP).
Nice to Have
Handcart with wide wheels - Fireflies need to transport their camping supplies from Upper Parking up the hill to their campsites, a 10 minute walk at least. A cart that can traverse dirt foot-paths will greatly ease the difficulty of load-in and load-out.
Large water-proof bags - Helpful in the event of rain
Written or printed volunteer shifts - Firefly is only possible because people are willing to volunteer their time. Write down your shifts just in case your phone loses service or battery charge.
Fancy attire or costumes - Fireflies are radically themselves and all are encouraged to express themselves however they feel is right for the.
Bug Spray - It's the woods after-all.
Seating - Your feet will get tired at some point and you will want to rest them.
First-aid kit - For yourself and fellow fireflies
Water-proof or water-resistant totes - Keeping your supplies clean and dry will help to keep you in good spirits throughout the week. Look for binds with lids that fit snug and can be stacked on one another to help with load-in and load-out.
Pocket knife or multi-tool with pliers - Something small, helps with cutting rope or opening packages.
Mallet - Drives stakes into the ground
Batteries - Nowadays most things are charged through USB, and having a larger battery pack can keep any of your devices with enough power throughout the week
Solar charger - While expensive, they are very useful in our electronic age. The tree cover lowers the effectiveness of solar chargers, but usually you can find people leaving their solar chargers in an area around the steam bath
