Since you will be so close you should plan a stop at Yellowstone Park, I have always wanted to go back again and I was there for a couple weeks last time. The hot springs,mud pots ,geysers ,and sulfer springs are something to see. All boiling right out of the ground and the wildlife is amazing.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
