I added another link section dedicated to local clubs. Its a little rickety since the Fells Point Chess Club doesn't have a website and a fourth club's website (Loch Raven Chess Club) seems to always be down to bandwidth issues.
Both have additional info at the Maryland Chess Association's Club Directory. Fells Point is particularly active, with one or more events every weekend. I'm heading back to the Catonsville Club tonight for some G15 action. I figured out the delay settings on my clock, so no clocking out while up a knight :P
I kept the listings to clubs in the Baltimore Metro area since I consider myself a "local blogger". There's a half dozen or more clubs in neighboring counties, and their listings are also at the MCA site.
