I go as rarely as I can, but where I live copperheads are a danger - and we have three dogs that spend a lot of time in the backyard during the day. I have to keep it down to a minor jungle back there, or I spend all my time worrying about one of my bebes getting fanged. Interestingly, the front yard doesn't bother me a titch when it gets knee-high even though I know it makes the neighbours twitch.
