I had heard the term for a long time but never knew exactly where it was. I looked on a map and the whole western part of the state looked pretty hilly to me but I don't know why I thought it was the panhandle area. You're right about it being pretty though. I've never been there, but a lot of magazines like Country Living and Country Home have done articles about homes and ranches in the area and I've always thought it was just gorgeous.
Prettiest part of the pandhandle is Palo Duro Canyon.
