Did the Hoover Dam several times myself (before and after 9/11 with all the security). Have someone with me that never went there. Walking between time-zones with Arizona also good for 5 min. fun :)
Driving to Laughlin today.
I hope to show the little Eddy's/mini tornado's or whatever one calls them, when on the plateau. I like it when they cross the road when you are just there but only was lucky ones in the past. Then you know why they want you to drive with your head-lights on.
