Man, oh man.
This weekend, there is Art and the Vineyard. http://www.artandthevineyard.org/ Also known as "The Pacific Northwest's Premiere Art and Wine Festival." We have been the last few years and we've dubbed it pretty much the best weekend of the summer.
And then, the following weekend? The Oregon Country Fair. Woodstock meets Oregon forests. Hundreds of arts vendors. Homemade food. Bands worthy of rockingoutness. Time to bring out the tie dye and handmade skirts. http://www.oregoncountryfair.org/
