I have bad sections of road around here too though the speed limit is only 45 (55 effective ). No shoulder (even the white line is eroded away in some places), no bike lanes and many of the vehicles on them are jacked up wannabe monster trucks & SUVs that take up most of what lane there is. I tried the ride a few times and realized that I want to be around to enjoy the environment I'm trying to preserve so I'm back to driving. Someone else said it best, it's all about the acceptable level of risk.
