Mountain bicycle

Year ago I bought a mountain bicycle as a backup bicycle.  I rarely ride it as I prefer my road bicycle.   I'm now going through withdrawal symptoms from bicycling while I wait for my new bicycle tires.   Donna suggested I ride my mountain bicycle.  I got the bicycle out of the garage.  I hadn't ridden the bicycle in so long the tires were flat.  I filled them with air and rode the bicycle. Because it is a mountain bicycle I only ride it a few miles each day.  But this helps while I wait for my new bicycle tires.
