Still primitive camp a couple times a year, including an annual 3-day canoe trip with different overnights along the way. (Plus an additional pre-trip day in my yard as everyone pulls in the day/night before)
No pre-planned stops or sites, just collect firewood and pull in about 2hrs before dark.
The rest of the time is spent navigating the waters in "paddle powered" canoes or floating with the current, LOL.
Half the time we stay up all night fishing and sleep on the river the next day.
By the end of the trip we look like we've been out for a month.
Some whitewater, but mostly just unpopulated areas.
