If you like food blogs, keep your eye on the Baltimore Snacker who is going back on the road.
In 2007 and 2008, the Snacker drove to each exit on the I-695 and checkout the food options. The summary is here. The posts were fun, and they were an inspiration for my "tour" of Howard County. This week, the Snacker announced that he is going to check for new places, places he missed, etc. You can poke around all his "Snacking Around The Beltway" posts or keep an eye for the new ones. He is looking for suggestions around Catonsville.
