I'm pretty new to this since I've only been commuting the past couple of weeks but I didn't get to bike in today and I miss it already. Yesterday I got off of the train one stop too early so I could have a longer ride home. I worked out a route on back streets using mapquest and it estimated a 4 mile trip. Not bad for me. I only had to get on a major street for 0.5 miles. I've already mapped out a route from two stations back That should add another 2 miles.
