I do.. I might be tempted to create one if I thought there were more cycle commuters in my area that would benefit. The roadies all go out in packs wherever they want and have the safety in numbers angle, but when you are the lone ranger, having a safe route is crucial.

Edit: I was really strong on the commute home today, because my bf pissed me off right before I left work. I ended up muttering replies under my breath most of the way home until I realized that I was getting strange looks by pedestrians. I freaking pounded up this huge hill though...
