I shot quite a few wild Bobwhite in Southern Maryland and on the Eastern Shore in my 28 or so years in the D.C. area. Wild Bobs were a lot easier to find in "The Free State" then in "The Old Dominion", and closer to where I lived. After a decade or so of not seeing any in the Shenendoah Valley where I shot Doves, I was seeing coveys again just before I retired and left -- 2001, 2002.
