personal highlights

1. Commuting: I bought a bicycle on my first day in town and love it!
2. Pedal Revolution: non-profit bike shop with a social engagement
3. Bike friendly: there are many green lanes throughout the downtown
4. Cracked asphalt: big holes are the nightmare of every biker / cyclist
5. 50 Hills: can be a sweaty challenge, but always keeps you in shape
