Thanks for the comment everyone.
;-) we don't eat them around here, at least not anymore. I do know that they used to.
Larry, sometimes we have lots of rabbits, and sometimes we don't hardly have any. Right now there are tons of them.
Angie, it is quite easy to walk by them. If they don't move, they look just like a rock or clump of snow.
Alice, I have never really found them to be terribly destructive. Although a few years ago, when we had a bunch of snow, they did eat away at a few square bales that we never got picked in the summer. They don't usually get shot at around here, except for cat/dog food once in a while.
cfpinz, they do turn brown in the summer, and they don't sit nearly so still then either.
