July is “Craft Brewers Month” in Oregon and the first big festival is this Friday through Sunday at Overlook Park in north Portland.  Craig Nichols organizes the North American Organic Brewers Festival.  He says in addition to serving beer in bio-degradable cups, the festival also encourages festival-goers to ride a bike or take mass transit.  The Organic Brewers Festival is noon to 9 p-m Friday and Saturday and noon to 5 p.m. Sunday. It's free to get in, but a tasting cup cost $6 and tastes are a $1 each.
