Camped on a sandbar in the river... we always took 3-4 small boats. All of the women slept in a boat after I talked to them... guys ignored the weather forecast and tossed a sleeping bag on the sand... river came up 2 feet overnight and they all woke up soaking wet. They listened to me after that... could sleep 2 to a boat by packing gear between the bench style seats to make a platform. Or we pulled up on the bank where we had 6' of rise to be above any flash flooding. Those low sandbar islands were only 1 foot above the water. Great to catfish off of but bad for sleeping!
