... however, a brick from the Mapes is something I definitely plan to have laying around the house someday.

Here's a piece of concrete that spawled off the St. Johns Bridge. When they built the bridge in 1931, they put the rebar too close to the bottom in the sidewalks. Then, over years of not keeping the surface properly sealed, moisture gets in, causes the rebar to rust, and it causes pieces of concrete to break off the bottom side. Some pretty big chunks have been found in the park under the bridge. Us neighborhood activists had a fit because we felt it made our park unsafe. So they put up netting under the sidewalks to catch the stuff, until they could rebuild the whole bridge deck. I think that's supposed to start this summer. Somewhere I have a front page newspaper article of myself and 2 other activists holding handfulls of this stuff for the reporter. (Can anyone guess what color the bridge is painted?)
