Rick,
We were in Vegas in October and I brought a couple of magazines home with me. One of them lists these tour companies:

•Sightseeing Tours Unlimited (702) 471-7155 (Visitors Choice award winner, whatever that means!) Offers bus and helicoptor or small plane tours, including Laughlin.

•Magic Tours (702) 380-1106 Offers bus and helicoptor or small plane tours, including Laughlin.

•Las Vegas Tour & Travel (702) 739-8975 [ditto]

I don't know what they offer, but at least it's a place to start! Of course, I've seen the ads 100 times for the free tours to Laughlin, but now that I WANT to find one, I can't!!

Good Luck, and great chippin'!!!
