I think this map could really do without the three-way chop of Anne Arundel. Is there any way to make that possible without really screwing up the rest of the map?
I just tried seeing if swapping land between 3, 4, and 5 could fix things- give 3's portion of AA to 5, have 3 dip into Prince George's, have 4 fill out more of PG but stay entirely within the county.
It didn't work- 5 is overpopulated. Some county has to be tri-chopped, or 4 has to leave PG, or you break up Howard, or something. I'm pretty sure Anne Arundel has a far less cohesive identity than most other counties, since part of it is Baltimore suburbs and part of it is Southern MD, and part of it is Annapolis and part is BWI and... you get the idea. That chop has to go somewhere, and AA is the least bad option IMO.
