I’m far from what many label as a bicycle advocate. While I think it would be really great to commute and conduct errands using a bike; and reduce our car usage, I also think that there has to be a political and social climate to support these things, as well as an infrastructure. The emphasis on living close to where you work is a valid point, which makes the idea of bike commuting a lot more realistic.
But I think if the planets are alligned, people would be willing to give it a try. I ran across this entry about a new bike service in Barcelona, Spain that is taking off. Could you imagine dedicating street space to biking lanes in Harrisburg? How much gas, pollution, and parking spaces could be saved with such a system? Plus then there are space usage advantages with encouraging more plazas and parkways/paths… and the health benefits.
Seeing something like this certainly gets the brain working.
