I'm fairly certain this is Oblong-winged Katydid. The length of the legs and the distance between antennal sockets put this in the genus Amblycorypha as opposed to Microcentrum. The deeply lobe on the humeral sinus of the pronotum eliminate the rotundifolia complex and the lack of dark marks on the edge of the pronotal disk eliminate the uhleri species group and this leaves us with the oblongifolia complex. Oblong-winged Katydid is very common in this area, Carinate Katydid (Amblycorypha carinata) is also hypothetically in your area, but it is the end of its range and is quite uncommon. You didn't by any chance hear it call did you? I'll probably just leave it at genus because it is impossible to eliminate the possibility of Carinate.
