>>535173I was going to recommend 5-gallon buckets with a good lid. They're cheap and reliable.
>>535134The MSR Whisperlite International is a good stove that uses pretty much any liquid fuel. You can burn gasoline or kerosene which are easy to find. This way you don't have to rely on wood or spend time cutting it and can always make food even if it rains the whole time. Fire cooking is great though. Grill baskets are easy, you put your meat, veggies, etc inside the wire tray and prop it up over the fire. Hardwoods are the best cooking woods. A cast iron skillet or dutch oven is great for over the fire.
>>535233Yes Yes. Bring the cast iron dutch oven, eggs, milk, cheese, bacon, beer and make some good damn river food.
>>534363One canoe takes the tent and rainfly, the other takes the poles and stakes, etc. Usually you can get the weight to even out. Though you might want separate tents for sexy times.
The pic is the gear for 2 people, 3 nights, 1 dog: one dry bag, one bucket, one cooler and one small backpack. Dry bag/bucket for sleeping bags, clothes, first aid kit and stuff that really cannot get wet. Backpack for stuff that can get wet, stuff in ziplock bags, and things you'll need a lot (knives, map, compass, GPS, whiskey bottle). Cooler for all the food, cold and dry, plus pots/pans and utensils. Use frozen water bottles - nothing will get soggy in melt water and you can drink it towards the end of the trip. Ties things to the thwarts (crossbars) in case you capsize you won't lose anything. That probably won't happen, but better safe than sorry.
Good luck and have fun! Canoeing, camping, fishing and eating fish are four of my favorite things. You'll probably want to do this again, so your gear will be a good investment.
