I have had WAY too much experience with that. I woke up one night, and (literally) heard a bunch of munching. I opened the front door and saw a buck and a doe mowing my hosta. I scared them away, but my hosta wasn't)t lookin' too good. There was only one leaf left. It grew back better than before, so I guess I was semi-thankful for the deer mowing it.
But other hostas of mine haven't had much luck when it came to deer.
