I have read MCN for more years than I care to mention and I have always wanted to add something. So here is my picture taken at the four corners monument which celebrates the intersection of Utah, Colorado, New Mexico and Arizona. It's the only place in the USA where four states are neighbours.
We have just returned from riding around the Grand Canyon on a rental Goldwing (they don't rent my ride, an Intruder 1500) for 2624 miles of some of the most beautiful scenery in the world. Part of this ride include the Williams to Kingman section of Route 66. An awesome experience riding on flat roads which stretch into the distance for miles and NO CARS for hours on end. A bikers paradise.
