Great letter Mimi. I'm glad you included your age. I hope it inspires other "older" commuters.
You've inspired me. I used to commute at least 3 days a week in Edmonton. I can't here because I have to cross a toll bridge to go work and it does not allow cyclists or pedestrians!!
My community is *supposed* to be ecologically minded and yet you cannot cross the only bridge over the Columbia within 20 miles with your bike. WTF.
So I think it's time to write a letter.
Living life like there's no tomorrow.
