Moving to Iowa!
I just cruised through Iowa last week. Nice clean air, way more humid than it is out in the West. The jeep probably picked up 10-15 hp at the lower altitude. You may have to rejet your carb for the air (much higher density). Fairly hilly country in Council Bluffs. Bring a fishing pole, I must've crossed 10 rivers and seen all kind of ponds and lakes I wouldn't mind checking out.
People from the Midwest like to party. Don't get into any drinking contests with any of them, they'll drink you under the table. :-D
Good luck, have fun and enjoy the change of scenery. Hope this helps.
