The last time I went on a group canoe trip with my brother, my uncle, and some friends, we found the worst possible place to sleep.
You are permitted to camp on any of the islands/sand bars along that section of the Wisconsin river.
Usually, you try to find a bigger island a with some grassy areas/a bit higher off the ground
My brother wanted to stop for camp early in the afternoon on a small low island. We set up like 12 or so tents for the 24 of us, and tried to make the most of it.
It was very windy, many of the tents collapsed.
It was very wet since the island only rose like 1-2 feet from the water level.
The tent stakes didn't hold very good since it was damp sand, there was no proper dirt/soil to get a better grip.
It never cooled down, it was abnormally hot year during a heatwave in July.
Woke up wet, hot, inside a collapsed tent sore, sunburned, and with heat exhaustion.
Uncle and I said fuck this, we packed up the tent, got in the canoe, and went downstream the 3-4 miles to the very next possible launch/pickup place, went to the car, drove to a hotel with 2 double beds and AC, and cooled off. Then we went to eat steak at the nearest gastropub.
I still like to canoe, but, wont go if its more than 75 degrees outside, and, wont go overnight any more even though other trips in the past were excellent fun when we found better islands to camp, and when it wasn't so damn hot or windy.
