I would suggest trying to stay at Idaho Dunes RV vs Sand Hills. Much easier access to the dunes. Bababouy's buddy opened a new brewery up there, so you may consider checking it out. Jackson Hole / Grand Tetons is a nice day trip. If you do go to Jackson take the long way on Hwy 26 through Swan...
You sure that's an SU ? Here's another one in the same price range.

Go pick up a used Yamaha Blaster and let him learn to ride just like the rest of us did. He will pick up using the clutch in no time. That quad will rip all over the dunes with a simple pipe and jet change. One of the best bangs for the buck IMO.
Very cool. Thanks for sharing. I have a relative that I was named after that was onboard the USS Arizona and died during the attack at Pearl Harbor. He was my dad's favorite uncle.
