Up until recently, I've had to drive 30+min away to a distributor to buy a keg. Then I decided to create a Google Maps-mashup website, similar to GasBuddy.com, to map where I can get kegs and their prices. I just started last week, so the site is still in an "alpha" phase, but if you guys think it might be worth continuing, let me know. I'll need lots of user input, as GasBuddy does, to keep prices updated. The site is at
KegBuddy. It also includes breweries that sell kegs of their own beer.
