What did you do to celebrate Earth Day yesterday?

I live in a big nature zone and am passionate about our planet. Did you celebrate Earth day? Attend any special community events, support any conservation causes? Right now I am tolerating the first mosquito of the season buzzing around my head and have abandoned my hot tub in favor of a pair of mating Pacific tree Frogs. I also support my local “Friends of the river” and participate in keeping our river and trails clean and beautiful. What about you?
