Field Work Suggestions?

Alright, so I've covered the U-district and Capitol Hill this weekend but found virtually nothing that is of any use to us (ran into 1 person wearing a Che shirt). I've contacted the Northgate Zumiez by phone and went into the Hot Topic on broadway, and neither were selling Che clothes that I could see. The Hot Topic manager did not really have an answer for me as to why that is. Anymore good ideas for places we could go to that we haven't already?
