Comprehensive mobile app for campsites/grounds/rules

Have done many Cracker Barrels in many states, and have stayed overnight in several. Have always enjoyed their food, and the prices are not out of line. However, the one in Jackson, Tennessee which is close to us, has suffered some during the crunch times. Visited there for lunch several days ago, and the food quality was definately DOWN. We will watch and see, hopefully it was just a bad day.
