These are Claire and Scot sitting on Grandpa's bike. Grandma's bike is the pretty red one in the background, but the size discrepancy isn't as amusing on her bike because she has a normal sized motorcycle, so I used these shots.
If you're interested in the nitty gritty details of my parents' trip, they have a blog about it. (It's a work in progress.)
