Ok, guess I will be the first serious reply!
Last year I assembled the local brownie girl scout troop (my daughter is a member) and I donated a dwarf newport plum to a local retirement home, where I supervised a bunch of girls planting and mulching the tree, amid local newspaper coverage.
The home got a free tree planted, the girl scouts received a merit badge, and the pics were run in the local 2 papers about 6 total times throughout last year. That was my award. Total cost to me, $20 and an hour of my time.
Haven't decided about this year yet.
