We're headed to Lair of the Golden Bear for week 2 this year, a change from the three previous years. This is my list of things to bring to Lair of the Golden Bear copied from the official source, Bad Mom's blog, and my previous blog entry on the topic and renormalized.
Edited 7/09/2009 & 5/27/2011 to add a few items.
Bedding and linens
A warm sleeping bag, pillows, and pillowcases
Electric blanket (This turns out to be a good idea as of 2010)
Heating pad (good to warm inside of sleeping bag)
A twin sized sheet and/or pad to cover the mattress under your sleeping bag. This prevents your sleeping bag from slipping off the mattress quite so easily.
Towels: beach towels, shower towels, and washcloths
Bring casual old clothing to stand up to the Lair's dusty environment. Be prepared for warm days and cool nights. There are washing machines at the Lair. Last year they were free as was the soap, but I'd hate to be surprised.
bathing suits (consider 2 pair for kids because this is the 24/7 uniform for certain ages and they get worn playing in the creek)
long pants - mostly for warmth in the evening
sweaters / fleece wear
jacket - it can rain, so a shell with a zip-in liner would be a good move here
hats: knit for cold nights and brimmed for day time sun protection
sweatpants that can double as pajamas
long underwear (also for PJs)
Shoes - hiking boots or trail running shoes
Aqua socks - for creek crawling. Better than an old pair of tennies.
Recreational and Activity items
reading materials, board games, playing cards
white t-shirts for tie-dye or t-shirt painting
fishing pole and tackle. 8-12 year olds have group fishing activities.
(die hard Lair campers will want to remember their softball mitts too)
swim goggles - chlorine in the pool is kept high
your own supply of bisqueware (they have only basic shapes).
your own garments for tie die.
For your cabin
Cabins have electrical outlets and a single switched light bulb.
Largish plastic bins for organization
ice chest (with a secure lid because squirrels and raccoons are hungry)
secure plastic tub for snacks
folding camp chairs
folding camp table
clamp on lights and extension cords
Exterior lights of some sort - Distinctive lights help you find your way back to the cabin after dark. Some people had novelty Christmas lights, or even the standard twinkly sort.
plastic bags for trash
hammer and nails (bring the hammer at least so that you can drive in a nail that surfaced over the winter)
screw hooks (if you aren't satisfied with using a nail)
Miscellaneous vacation needs
flashlights: at least one for each family member
laundry soap (in case there's none provided)
quarters (for laundry if it's gone back to a paid system)
clothesline and clothespins
markers for identifying your stuff or marking schedules, etc.
backpacks for everyone (makes carrying towels, etc. a lot easier)
cheese knife (if the pocket knife won't do)
churchkey (redundant if the pocket knife has one)
wine glasses (plastic)
sparkling wine stopper (provided you plan to have or save any)
moleskin for blisters (the first aid tent is liberal with giving this out, but you might as well be prepared)
Your usual plus:
A+D ointment. It's dry and this is great for chapped skin.
chapstick with sunscreen
Snacks - Just bring enough for the car and a famished kid emergency, though a cooler and juice or soft drinks are quite nice. Food is so plentiful at meal times in camp that it's really overkill to bring more. The water tastes delicious there, so I tend to enjoy a lot of that.
Adult libations - Wine to share at the lodge, after the kids have gone to bed or for cocktail hour get-togethers. Beer tastes better than usual at the Lair and it's handy to share.
