Ron, Are you looking for a shelter from the weather, or critters? I usually forego tents unless the potential weather dictates one. What people don't realize( and sleeping bag makers never mention) is that a bag's lower temperature rating is often measured assuming the use of a tent and appropriate clothing. A quality tent, with waterproof floor, sill and zipper fly will keep out the assorted snakes, mosquitos etc. No tent in the world will stop that bear of yours. My strategy is to find a campsite away from obvious animal trails and to keep all food stashed away from my sleepsite. You could also rig a simple alarm. String some cord on sticks around your camp and hang tin cans. Anything comes in will trip the alarm, sending the intruder ( and you) into a panic. <br><br>
