Oh thanks for that tip Marni. I also have SPD clips and didn't think about little rocks and dirt getting stuck in there. I've been on three rides and have done pretty well. My last ride I was with a friend and we got gabbing and I almost forgot to unclip once! I always put my left foot down and I knew that going in but the owner of my LBS tried telling me I was "right footed" and to put my right foot down first. I said "nope, this is what feels natural to me." My muscles are still getting used to pulling as well as pushing so I'm not sure I notice a difference on hills yet. Thanks everyone for the responses.
