Not everyone, but it seems most people prefer to stay in the shelters. I have tried shelters a handful of times, and when it is raining it is nice to be able to just walk right in, but for the most part I just about always setup my hammock. I just wanted to include a picture of a typical shelter and my hammock setup. One thing I should note, most shelters are rodent infested. Well that is unless they have a resident snake to keep the mice under control, and yes some shelters do have snakes living in them. I usually hung my food more to keep the mice out than to keep the bears away.
