A friend of mine is of a certain age, and some local clinic recommended that he exercise.
The clinic gave him a voucher for a free bike at the Bozeman Bicycle Kitchen. He picked it up yesterday, and they even hooked him up with a new set of lights. Good deal.
This place let's folks work on their bikes at a station with all the tools you'd need. You can also volunteer and get credits toward a bike of your own. It's a pretty cool operation.
Thumbs up to the Bike Kitchen!!
