That's cute about the bus driver! You know, I am always intimidated when there is a full bus or I'm holding people up, and I know I would probably wind up dumping out the contents of at least one of my bags...you know how that goes!

Did you take a bow when you got on the bus? haha...

It pays to have a second set of wheels. If you have disk brakes it will get pricey but it's worth it. I know I have a spare set and once when I got a flat I just used my second set because I was in a hurry AND I left my patch kit at work!
