I know that bikes are Transportation Plan A for almost everybody here. But you have to have backup plans to cover unusual times and situations when the bike won't work.
The other day, my knee hurt bad. I knew it needed rest, so riding was out. Plan B is to walk, but I couldn't do that either. So I took a sick day at work and took the city bus--Plan C--to run a couple errands that I couldn't defer. The next day, I was able to do some light riding, and today I can ride a little more. I hope to be back to normal by tomorrow.
It seems to me that failing to plan for different contingencies will often cause failure at being carfree. What backup plans have worked for you? What would you reccommend for people who are considering going carfree?
