There's the remains of a personal arboretum in Catonsville, and I picked up coffee bean seeds there a few years ago. I didn't know what they were so brought them home to id them! If that's close enough for you, google 'Lurman Woodland Theatre' in Catonsville. There's an open air concert series held in this wooded area in the summer and there will be a sign marking the road. It's either off of Mellor Ave or off of Bloomsbury Ave. The Lurman site should give directions. Turn down the road with the Lurman sign and just park in the little lot and start walking around. It's basically a public park, so you can park and wander and pick up seeds. Many of the trees there are labeled too.

OR....you could trade me for some. I'm live in KY now, but stopped by to read about the MAG swap (am a former Baltimorian, and I miss this swap. We have a nice one here, but no where near as large.)

Let me know what you might have to trade, and I sure can send a bunch for you. Have a tree behind my house, and harvested a good bit of these. (Grow the extras and swap 'em at next years MAG. That would be sweet.) They're large seeds, a little bigger than an almond in the shell.
