I didn't actually know that, TEd, although I did know that there are damn few lakes in MD and that the few there are (other than Deep Creek Lake) would more likely be called ponds in states where they have real lakes. We make up for it with the Chesapeake Bay, which is like having a large lake running right up the middle of the state and dividing it into two halves, which it did very effectively until the early 1950s, when the first bridge was built spanning the Bay. Up until then, since the mid-17th century, you got from one side to the other either by boat or ferry or by going up and around. Of course the Bay is not quite like a lake, being brackish to a greater or less extent depending on how far north you are, and subject to the tides.
