I was surprised at how rocky certain short stretches were in that area. But Maryland was a very neat walk with the original Washington Monument and many Civil War historic sights. Even though I was thru-hiking, I took three days to enjoy it all. Some do the whole stretch in one titanic 41-mile day, but they usually then take a day or two off to recover, so I figure I got the better end of the deal.
Glad to hear the rain couldn't squash your hike.
