We flew into the bottome, well half way down, of the GC and rode for four wheelers for 4 hrs. It was an actual working ranch that stretched up into Utah. When we got back from the riding they served us a simple but very good Lunch/dinner of a a great pulled BBQ and all the typical sides from a BBQ ranch meal. I remember the beans were really,really good. The only detraction from the trip was the four wheeler ride. A torrential downpour had hit a few days before and washed everything away leaving heavily rutted roads and trails making for an extremely rough gpoing.
One thing that was pretty funny. They offered an optional van ride instead of riding a four wheeler, this was for the older crowd mainly. I remember looking back in a few really rough spots and seeing all those people bouncing up and down, I'm certain heads were hitting the roof. I mean I laughed but I also felt sorry for them, almost 4 hours of that, I was even aching a little.
I'm sorry I don't rememebr the Co. but iyt wasn't cheap, but once in a lifetime so we did it. I think it was like 350 per but it was a while ago, maybe 10 years ago? Anyway it was great, rough ride and all. It would be an absolute blast if it were rut free.
