In college I did, but now I'm not really in an area where I can. Dude, they had the best trails behind the school. I remember once running when it had just started snowing and as you round a bend it opens up into a huge meadow. Anyway, there were like 2 black tail and they jumped a barbed wire fence. It sounds hokey now, but it was sweet. Man I miss it. It's so relaxing.
