Awww bummer Nuthatch. I have a schedule conflict too. I'm in need of a class to teach me some more stuff. I can change a tube, a tire, and clean my bike. That's about the extent of my knowledge Where did you find the date for the class, at the store or online? The Oakbrook store isn't too far for me to go to, so the next time around I hope I can go. Ready for the MS150?
