I love when I get paid to ride my bike! I am a city planner, and we are working on a redevelopment project, and I had to ride my bike to and around the site, which is about 10 blocks by 10 blocks. It's about 10 miles from my house, so I know I got 20 miles coming and going, plus the very slow, stop-and-go tour of each street, stopping to look, think, make notes, and be creative!
