Dalecan and Wiseguy,
if you're going to do some desert driving through Az, get in touch with the Z sports car club of Arizona. I went on some awesome road trips with them, we drove into New Mexico a fair bit. the Coronado Trail is amazing. 98 miles and over 500 corners. make sure you're all tuned up, those old folks don't go slow
THere's a really good stretch from Silver City, East to the interstate. I did it at 6am on a Sunday, wow ! there's a small town at the east end of the twistys, complete with a police car and radar. be careful.
As you can see from the name of the club, they've been around a while... http://www.azbmwz3.com/index.htm
