Remember that in Charlotte "Jeopardy!" is on first (7 PM) on the NBC affiliate, WCNC, and NBC will probably be in the middle of the U.S. Open at that time. I can't predict whether "Wheel" will get on at 7:30. In Greensboro, however, they are on CBS affiliate WFMY and the timeslots are reversed, so yes, you should be OK. What time and channel are they on where you're going?
