May is national bike month here in the US. So, to celebrate it - bought a bike last Friday. Been biking on the easily accessible Eliza Furnace trail (near my work place) for the past 2-3 days, and it's fun. It's a nice 8-speed bike and you really appreciate the  presence of gears when theres a uphill section in the trail (this is the first time I've had a bike with gears and with pedal toeclips). Theres also a Bike-to-Work Week from May 15-19 and Bike-to-Work Day on Friday, May 19 - don't know whether I'll be able to celebrate that :)
