Just an example of the massive numbers of people Grow Pittsburgh can get out to a workday these days.

Bandi Shaum field used to be a baseball field: after many years of disuse and abuse by locals (mostly folks wielding beer bottles which they threw from the cliff above, apparently) some landscapers by the name of Carolyn and AJ (pictured in main picture, shirtless and red-shirted) decide they could do better with what was there. So they draw up plans to turn the disused baseball field into a massive community garden.

Close to 3 years, it takes them, to push the plans through city council. Tons of neighborhood and city organizations had to approve it. Then they approve it. In less than a year from that milestone, they have what you see in these pictures, with the help of the South Side Slopes Community Foundation and GrowPGH.A lesson (I think): we could have more of these gardens sooner if there were less red tape, or at least a replicable process for getting around the red tape.

They get something like 40 volunteers over the course of the day:
