NYC, DC, San Francisco, Denver, etc. In fact, bike lanes have become so ubiquitous in NYC that I rarely use the subway or take a taxi when I'm there for a visit. When I travel in Europe, I usually end up biking most places I need to get to.
All over Colorado (Ride the Rockies - 4 times; Bicycle Tour of Colorado - 6 times) Do a lot of training rides at the Air Force Academy, and in Denver. Iowa (RAGBRAI - 13 times). Did the the from San Francisco to LA this June. I have also biked from Vienna to Prgue.
Just ran across this thread through fellow cyclist's profile, so I figured I'd zombify it and make it live again. Bwahahahahaha!!!!!!
