I just purchased a BikeLink card and would like to urge others to do that too. Here's why:
I often don't use my bike for errands or entertainment because I don't want to leave it on the street. Having low cost, secure bike parking everywhere would encourage use of bikes as general transportation.
Even though there are no BikeLink lockers in my area, I think by buying them, I will help drive businesses and government agencies to consider providing them.
It's sort of a "chicken and egg" argument and I have decided to a take a stand for moving this forward.
