How did you celebrate earth day?

Went to work, burned several dozen gallons of diesel in my pre emissions company tractor, then filled up the gas tank of my Bronco, came home and ate some homemade pizza, drank a couple beers, and went to bed. Almost forgot, I cursed global warming while I was freezing my *** in the unseasonably cold snow and rain mix of the day.
What's an Earth day?
