Very nice! I think urban farming including rooftops, vacant lots, former lawns and whatever, is the wave of the future, in a back to the future kind of way. People don't remember the Victory Gardens of WWII (I don't "remember" them either,
, but I've read about them). During the war the cities produced much of the veggies for themselves while a lot of the farm produce went to the troops and to feed our besieged allies.
