In an attempt to feel better and eat more pizza, I took up bicycling. immediately my frustration was figuring out how to safely get from point A to point B. Google Maps ability to overlay arbitrary lines onto clean looking maps seemed like a great opportunity for me to just make the mapping software I wanted.
At the moment the site is lacking some features. It doesn't work in IE, and you can't do much more than draw lines. However, I feel that it is a start for usefulness. So please use it. If you'd like it to do something else or something more to aid in your bicycle treks, let me know.
