POULSBO ­— Poulsbo’s three breweries are teaming up again to raise money for North Kitsap Fishline.

Here’s how it works.

Purchase a 10-stamp Passport at Slippery Pig, Sound Brewery or Valholl Brewing for $5 (donation to Fishline).

Every time you buy a beer at any of these breweries, you get a stamp (four for a Growler). The brewery will donate 50 cents to Fishline for each stamp.

The brewery with the most stamps turned in on Aug. 17 wins a barbecue at that brewery. Your filled-in passport is an invitation to the barbecue and a raffle ticket for a multitude of beer related prizes.

The barbecue will be held on Aug. 25. Invitations and directions will be sent via email.
