I travel a lot on business. (Too much probably.)
I get to see cities in a way most folks don't.
Most recent trips:
Phoenix - rented a Felt 29er Hardtail.
San Francisco - delightful Mission Bicycle 8-speed.
Helps keep the home stable (The Noble Steel and T.A.R.D.I.S.) to two.
BTW, BYOH - highly recommended. Not thinking "a head" kept me from riding in Paris.
