Yesterday, just as the weather turned for the better, Oktoberfest Tacoma consumed Opera Alley. The scene was more "harvest" than anything remotely Bavarian with corn stalks and pumpkins scattered. The breweries brought their pumpkin beers, as well as stouts, IPAs and seasonals. There wasnâ??t any sign of cleavage, suits of armor or crowns. What did fill the downtown Tacoma alley was smiles, conversation, pretzels and lots of beer.
