Nats should hang onto Maryland. Bowie and Frederick are left over from the 33 year interregnum. Montgomery County would be great...where did Walter Johnson own a farm? When I was a kid -- in Michigan Park, NE and then PG County -- we despised the Bush League Baltimore Orioles. Frederick is handy because it's just down the road from Harrisburg. Or put the Nats AAA team at RFK. If the closed off the upper deck, RFK holds about 20,000 in the lower bowl. No drastic investment in a new ballpark. In contrast, the Mets AAA team is now in Las Vegas...a long trip to any of the NL East cities.
