Today is Widmer’s Brother’s Day: the day that Oregon Governor Ted Kulongoski and Portland Mayor Tom Potter declared a state holiday, and Widmer is celebrating for a good cause:

To honor Brother’s Day, Widmer Brothers Brewing has pledged to raise $10,000 for Big Brothers Big Sisters by August 11 and is making it easy for those who love their bros to help, with a collection of e-cards at www.widmer.com/brothers. More snarky than sentimental, for each e-card sent $1 will be donated to Big Brothers Big Sisters in support of the organization’s effort to recruit more volunteer Big Brothers.

Facebook junkies can help Widmer reach its $10,000 goal, too – the brewery will donate $1 for each person who “fans” its official page at www.facebook.com/WidmerBrothersBrewing this summer.

But that’s not all: Widmer is also celebrating down at the Gasthaus Pub today from 4 until 8pm with live music, food and drink specials and bros vs. bros competition. I don’t know what the “bros vs. bros” will be about, but I’m sure it’ll be entertaining.
