I decided to go back to college to finish my degree (20! years after I started), so switched from work to school in January. It was seriously rainy and cold so I took the bus for that entire month. I rode to school once last week. Today, I decided enough was enough and started my commute with riding to the LBS to drop off my bike for a tune-up.
I took the hilly instead of flat route and was surprised at how OK I felt despite being off the bike for six+ weeks. I was super slow, but since it wasn't rush hour on Seattle's finest cat-6 route it wasn't a big deal.
