Talk about a treasure map! Check out The Baltimore Beer Guy blog for a map of the HoCo scene for suds.
The blog comments about beer, and it has a spectacular side column of links to beer events, restaurants, homebrewing resources, and dozens of other beer sites, blogs, etc. The blog is nicely written. It is densely-packed with real information about places, events, etc. Looks like unique information for the local beer nut, but still accessible to anyone just thinking about where to go out tonight.
The local highlight is the Howard County Beer Map. The pretty young things at the Washington Post's Going Out Guide don't make it to Columbia, but Brian has cased the county and recommends places in both the HoCo map and another of Good Beer/Liquor Stores. He also has posts about places like Dog Pub, Frisco Grille, Victoria Gastro Pub, The Perfect Pour, etc. -- click here and here.
