Earth Day is upon us, which in Seattle means a day (or this case's year, a weekend) of green-tastic events. If you don't have it in you to plant a tree or don't want to take the leap to living in some crazy compost house of your own design, try something a little more mellow like the 2012 Green Home Tour. It's two days cool walk-throughs of new builds, remodeled and/or retrofitted homes, as well as how to make your house more energy efficient and overall more green. And it's free! And it's kid-friendly! And you get to choose exactly what you want to see and do! Hip hip hooray for Earth Day!
