Hmmm...counting just states, I've seen Hawaii, Washington, Oregon, California, Arizona, Nevada, Idaho, Utah, New Mexico, Texas, Oklahoma, Louisiana, Mississippi, Alabama, Georgia, Florida, North and South Carolina, Virginia, Wisconsin, Illinois, Indiana and Ohio. The best was probably Illinois in the summer. The worst was probably Illinois in the winter. Go figure...
I'd love to see the New Hampshire/Vermont area before I shuffle off, preferably in fall.
