Sometimes there are spirited discussions about parking in Phoenix. This is the place for them. By the way, if you'd like some good background on the relationship between parking and urban vitality, I suggest checking out these two books by
Donald Shoup:
The High Cost of Free Parking (in-depth and somewhat technical)
Parking and the City (a shorter and more accessible follow-up)
You might also want to look at the
Shoupistas Facebook group, where people discuss parking reform.
