Yes and no. I am definitely boxed in by where I live, but I don't necessarily feel boxed in on the bike. My preferred roads are 4-lane 45mph roads, which make up most of the town. My least desirable roads are two-lanes, and the higher speed country two-lanes are where I would most expect to die. You know, the roads all the roadies go to to be "safe".
I make one detour to avoid one stretch of road. Unfortunately, I live off of one of the only roads in town I would rather not ride on. The red is my detour. The most troubling sections of what's left are the two-lane roads, not the 55mph 4-lanes or the big intersections.
