I agree that BGW has always had a very liberal alcohol policy and other parks are just catching on. I thought it would be fun to have some youtube videos outlining alcohol policies for various parks. Just for the record, the parks I've been to with a good selection of beer and few limits on where you can take your drink are KD, SF Georgia, SF Great Adventure, Universal Parks, Cedar Point, BGT, Sea World, Hershey Park (okay selection). My wife was self conscious walking around Hershey with a beer. @horseboy makes a good point that the park may be limited by Maryland law.
