I'm in Sunnyside, I sometimes OC in Yaks when I'm there, but I'm not there often. Right now I'm OCing everywhere cuz my license expired a few days ago, still waiting on the renewal.
I like your idea. I'd like to participate. I've been meaning to do similar things around the valley, I've been hearing stories of a few towns down here where people I know have gotten arrested for refusal to ID, even when not detained. Yakima seems a good a place as any.
Where do you live by the way? (or PM me that if you prefer)
