I can't imagine giving it a second thought.
If it were raining outside and dry inside, or free from bugs, if it were the best place around in which to sleep, and I was tired I wouldn't care.
I walk through "my" woods at night to the horror of the neighbors. I figure I'm meaner than anything likely to be found there. What the hell. (And the dog would warn me if there were anyone around. I'm not quite as foolhardy as it sounds.)
