Yeah, depending on your route you could hit up Baltimore City or Ocean City.
Depending on the time of year you could see an O's game (and for cheap too since they suck) or a Ravens game.
Depending on your interests you could go to a vineyard for a wine tasting or hit up the clubs for some drinking and dancing!
Natty Boh! even though its not made in the 410 anymore.
Tons of historical sites to visit in MD, including Annapolis with the Naval Academy, Antietam/ Sharpsburg (Civil War battle), downtown Baltimore with the inner harbor.
You will definitely HAVE to get some crabs. I always enjoyed driving around and looking at the scenery. I use to live in MD but moved to SC and that is one thing I miss the most, SC just doesnt have the same back roads as MD.
You need a reason to visit MD i ll give you one CRABS!!!!!! not the itchy ones from Curtis bay but the blue pinchy ones from the Chesapeake bay.Other states have crabs but they all try to cook them like us!
