In MD, add Seneca Creek State Park and Patapsco -- two awesome courses and shouldn't be missed on any list.
In DE, you can drop Bellevue and Lum's Pond
In PA, add Unami Creek (9 hole), Whispering Falls, Codorus, Quaker's Challenge, and Lehigh Valley
In TN, I don't know how you missed Cedar Hill, but it's awesome.
In TX, add East Metro -- best course in the state; also add Williamson County, Veteran's Park, and Z-Boaz.
In VA, you've got a bunch of courses that don't deserve being on the wish list: cut Pohick Bay, Bull Run, Burke Lake, Gillies Creek and Newport News. On the other hand, you should add New Quarter, Dorey, Giles Run and Hawk Hollow.
