Thanksgiving in Canyon/Amarillo
Both Canyon and Amarillo have websites,certainly Amarillo does.
Check out their Chambers of Commerce.Some of the Amarillo hotels should have something.
Maybe other places too. I wouldn't mind going to one of the buffets in downtown San Antonio
at the hotels or a few other places, but I don't want to spend 30 to 50 dollars for one person,since Christmas is coming up.
