I took my dog (German Shep) out for a run last night, like I do almost every night. It keeps him from going ballistic in the house at night. On the way home this dude proceeds to scream profanities from his truck window about how I am going to kill my dog by running him while I am on a bicycle. So, of course, I gave him my opinion politely. I just thought it was hilarious this guy was so pissed about running a dog. The whole trip is maybe 3 miles and a majority of the time he is pulling me and he gets all excited when I get the bike out of the garage. I am pretty sure he enjoys it a lot more than just walking.
