Finally kicked off biking to work today on my 15-yr-old ratty mountain bike. It was wonderful, around 50 degrees and sunny. About 4 of the 5 miles were on empty, peaceful residential streets. Even with a heavy backpack holding my purse, lunchbox, locks and a change of clothes, it was so much more enjoyable than taking the bus and about the same length of time. Can't wait to ride home! Hoping to start off 5 for 5 to make this a habit
