I use Boisefort Valley Farm . . . normal delivery is early June--October or so, and you get a good mix of veggies & fruit, + a weekly bunch of flowers, all from their farm. They were one of the farms washed out in last winter's Chehalis flooding, but they seem to be going strong again. Lots of good root veg, peaches, berries, occasionally mushrooms, great (huge) lettuce, apples, etc.
Here's a link to their site if you're interested--I've been completely happy with their stuff for the last few years!
