We have some of those “project 21” type set ups in our area too! (Glenn Beck would shudder) They are fun to visit - walk around to various places to drink or eat - live entertainment in the square and even shopping available. The problem is parking. It is a bitch to find someplace to park, however, for $400K for an apartment much smaller than our current house, just to get two parking spots, seems a bit much. ;^)
And just try peeing off of the porch, or shooting off firearms or fireworks at one of those places.
