Pretty tidy stadium that.
Yeah they are in the process of turning it from a baseball stadium into a soccer stadium as we speak. Looks like it will be just the right size and it's cool too because it's below street level so you can look into the stadium from the road, behind the East Stand. It also happens to be right in the middle of the city unlike a lot of new MLS stadiums that are built on the outskirts.
Fast wanting to support Portland!
As far as I know it's the oldest continually run soccer organization in the country.
