Sounds like you've got some good gear Andrew. I'm running this tent:
I had a Coleman but we used it on our first trip to Algonquin and someone had left shampoo open inside. Bear decided to rip one of the walls to get in. Fun fun. We weren't in it at the time.
If I could recommend some stuff for people to bring:
Necessary
Tent
Foam/Inflatable mat
4 lb sleeping bag
Flashlight (gotta be something like 500,000 Candle power otherwise it's just not worth it)
Crank/Fully Charged Radio (Even tho we're in a radio-free zone, a radio is always safe to have, and keep very quiet in your tent to check weather forecasts and whatnot)
Cooler (even a small one will do, just to keep food/drinks in)
Food/Drink
A Saw (dunno if there's a cheap wood yard around Pog lake, but personally I find it easier to just go in and find a fallen tree. I'll be bringing mine, so anyone that needs it can feel free)
Bug Repellant!! (Especially true if you like going into the forest to find wood for the fire. Remember, we're going just a week into June... smack in the middle of both blackfly and mosquito season. Both bugs are very prevalent in Algonquin at this time... blackflies moreso as they are attracted to clean waters rather than standing, murky waters like Mosquitoes. Also starting to make their appearences at this time are horse and deer flies... and these bastards can bite. 15% DEET formulae, such as OFF! Deep Woods are reccommended)
Garbage Bags
Rope (I normally camp in the interior, so this is a necessary accessory, used to hang the food pack. Other than that, it's good for hanging clothes in the event of getting stuck in the rain, among other things)
For Fun/Comfort
Propane Stove I'm not sure if this is just recommended or necessary. I use it for so much... making hot meals, boiling water, occasionally starting a fire...)
FRS Radios (good if you're biking/hiking)
Binoculars (great for looking at the stars at night, or just nature watching)
Shampoo/Conditioner/Razor I dunno how stinky you guys get after 3 days, but personally, if I'm just going for the weekend, I'll wash my hair Friday morning and I'm good to go. And I think it's bad luck to shave on a camping trip
Bike Pain in the ass to haul around, but the trails are killer if it's not too busy
Floating air matress Fun for going out on the lake, or comfortable to sleep on. Overall, a good thing to bring along if you have the room
This is more than I've ever brought on a camping trip. Normally I'm good to go with my tent, lighter, sleeping bag, pillow, propane stove/lantern, 5 canisters of propane, saw, rope, clothes and food... but if you want the experience to be really rewarding... pack it all up!
