I guess I forgot to mark it off, but I spent a Saturday in November planting trees! I found an opportunity through The Nature Conservancy to help restore the area around a salmon stream. I guess a team had come in before and cleared the area of invasive plants (blackberry bushes, etc) to make room for trees and other plants.
So I drove out to Issaquah to met up with a group of a dozen or so people and we started digging holes and filling them with the hundreds of potted vegetation that was donated. I think I must have personally planted 30 – 40 separate plants. It started to rain a bit before we were finished so I ended up quite muddy. It was quite a fulfilling experience!
