My ride is 3 miles one way, mostly flat. Slight slope at each end so I'm starting each ride up hill. I ride residential roads most of the way, save for the ends. At the beginning, I cut through some parking lots to avoid a left hand turn across a busy, dangerous intersection. At the end, I have to hop on a main road to go over an overpass followed by an immediate left. More often than not, I ride a bit farther up and turn around in a driveway, a lot of people make a right off the ramp at high speeds and cars essentially come out of no where.
It's a nice ride, when it's not hot. Sure do wish we had better roads, though. I spend a lot of time dodging tire-eating pot holes and cracks.
