Yeah, Sisters is just down the road. Funny you mention wildfires, as the last time I went through there, the entire town of Sisters was smokey, the sky was burnt orange at noon, and it was literally raining ash from a nearby wildfire. Combined with the drive right past the extinct volcano, I thought I'd taken a wrong turn an ended up in Mordor. :-P Drop me an email when you get to planning your trip details and we can work something out.
