I have a commute in Phoenix, AZ that is about 11-12miles. My first day I printed directions out. Missed a turn and added a few miles :/ Not that it's a bad thing. I was wondering if anyone could recommend a GPS app for a phone that might give you turn by turn directions. I tried the Google maps app (android phone) but there is no option for bicycle. I take a zig-zag pattern through the city to avoid the major streets. I did have to reference my directions a few times. I would also think it would be handy to have so I can go other places too. Lastly, I used my front brakes too much and had the back tire lift up a bit. When it came down the chain on the front gears came off. What caused this? Great website here!
