An article in today's Oregonian talks about the potential for Portland (or Seattle) to obtain an MLS franchise. I think Porland would be a great market for MLS. It seems like the Seattle option is certainly viable but perhaps not as strong as initially thought (hence the look at Portland). PGE seems more suited to the type of venue MLS prefers (25k or so) versus Qwest (around 70k).
