The Grand Canyon idea: Watkins Glen, NY - it is an awesome place and last I knew there was camping there, too. Vermont state parks are wonderful. And Maine is my very favorite place to visit (in the summer, that is - my Nana lived in Maine and breaking ice off the surface of a bowl isn't my idea of fun!).
Okay, so we who reside out here in sunny Cal have to resort to bribery to get visitors? All right. I don't have all the amenities that Sharon has, but I do have a large graveled yard, a 100 ft. extension cord and an outside water spigot. Is that enticing enough? No? How about Disneyland, Knotts Berry Farm, San Diego Zoo, Lake Arrowhead or Big Bear, Joshua Tree Nat'l Park, Palm Springs Tramway, Hollywood, Living Desert Museum, and some of the best white sandy beaches you'll find anywhere? Both Sharon and I live within 45 minutes of the ocean, the mountains, or the desert. Take your pick. AND we can offer the occasional rocking and rolling ground!
