OK. We are now less than two weeks away from our trip so here is the finalized itinerary. This is just where we are going. I will fill in what we are going to see later.

May 30 - Houston to Salina, Kansas
May 31 - Salina, KS to Rapid City, South Dakota
June 1 - Rapid City, SD to Rexburg, Idaho
June 2 - Stay in Rexburg
June 3 - Stay in Rexburg
June 4 - Rexburg, ID to Cedar City, Utah
June 5 - Cedar City, UT to Las Vegas, NV
June 6 - Stay in Las Vegas
June 7 - Las Vegas, NV to Page, Arizona
June 8 - Stay in Page
June 9 - Stay in Page
June 10 - Page, AZ to Carlsbad, New Mexico
June 11 - Carlsbad, NM to Houston

I know it's ambitious, but we probably won't pass this way again and we want to see as much as possible.

Anyway, I will post more later.
