I am what you might call an occasional bike-to-work-er. I ride when I can, I love it when I do, but sometimes driving is just too easy. Denver is a GREAT bike city. Ample trails keep you away from cars, and even when you're in the street, there are lots of "bike lanes" or at least signage to remind drivers to be aware. There are even fairly aggressive traffic laws that protect cyclists right of way.
In the 20 years or so that I've been occasionally riding to work, I've always skipped "Bike To Work Day". For some reason I rejected it, and didn't want to ride with the masses. This year, I decided to join in the fun.... and fun it was. What I always thought would be annoying turned out to be amazing and invigorating. To see so many people out on two wheels was refreshing and made me feel like part of something bigger. I mean - I see no less than 50 other cyclists every leg of my journey on a normal day - but today I saw HUNDREDS. And yet - the trails didn't feel crowded or too busy. There were a few spots where I needed to slow down to get through the masses at a refreshment station, but all in all - it was awesome.
