I too came on to talk about Maryland.  Seems someone beat me to it by a day.  I live in the 3rd district but used to live in the second.  Previously my hometown flopped between several districts.  The entire state is now Gerrymandered.  It used to be the 1st (Eastern Shore) and 6th (I always called it the Mountain District) were left alone with contiguous and sensible boundaries, but now even those have some funny reaches.  Pay particular attention to Maryland's 2nd and 3rd districts, they are like snakes or interwoven strings with small and obnoxious connections.  I agree with the comments above about (I assume the "new") districts 4 and 7.
