Tickets for the 2015 Northwest Green Home Tour just became available. If you haven't already, reserve your spot today. Tickets are free, but there's a new option this year thanks to a new partnership with Tesla Motors. If you make a donation of any amount when you go to reserve your ticket, you and up to three friends will be entered to win a two-hour chauffeured tour of the homes in a Tesla Model S. Two lucky groups will win. All donations go to support the nonprofit Northwest EcoBuilding Guild, which helps promote sustainable building practices in our region.
