I love this place (Rowell Bros, if you live around the Portland area) and have been there several times before. The price is amazing, the people are friendly and not snooty, and there's even a whole blueberry grove area that you can park and pay near. And, the sign when you drive up to the place says something to the effect of "All you can eat free!!"--which is good, because I am a snacker while picking. ;)
I went with my old friend Alyssa, and we had a great time catching up and filling containers with berries. I may have to go back some weekend soon while there are still things to pick!, but I also gotta hit up the U-pick peach place soon. They weren't quite ripe last weekend.
Although now I have a few too many, and I still had some frozen from last year. What would you do with an overflowing berry haul??
