I'm in IL, but sounds like you went through on 64. I'm on 70 if you went through Effingham (if you did you likely saw "The Cross" along the interstate) you went through Altamont, just west of Effingham, and that's where I live! Sounds like a very long drive. Like I said, my daughter lives in Price, UT. We figured it out one time, when she came home for a month last summer. From my house to her house (at that time), it was exactly 6 turns!!! And that included leaving the driveway. Very strange, knowing that it was about a 16 hour drive.
Sounds like you had a great time. Nothing better than good friends getting together year after year.
