What part of southern MD do you have in mind? The Western Shore or the Eastern Shore. The Eastern Shore is a whole nuther world. The further down & away from the highway you go, the further back in time you travel. The dialect is very much old English to the ear.
Drive out to the end of the road at someplace like Hoopersville & you almost feel like you are in the remote north someplace were it not for the air traffic in & out of Baltimore & Washington. There are some great SPs on the Eastern Shore too. Wonderful kayaking in parks such as James Island SP, Crisfield & Martinak SP on the Choptank River, Denton.
