Brown or black bears?

I was tarp camping in a chaotic "campground" in Jasper many years ago that was heavily infested with black bears. As I went to sleep, I was seriously concerned that the bears, which were everywhere, would trip over my tarp lines.

So maybe you want to put reflectors on the lines or something so the bears don't hurt themselves falling.

Or, the point is, that while all of the above posts are sound, it's possible to worry too much about black bears. My girlfriend nearly spoiled our vacation due to paranoia over this.

Unless at very popular sites, you probably won't see them and if you do, they're generally not much trouble. Think of them as big racoons.
