Hi all, Am new to this so hoping for some advice and help. Am flying in to Phoenix last week of May for 3 nights, then heading to Vegas fro 2 nights and then driving up north to Grand Forks to visit some relatives for a week. Am concerned about the route from Vegas to Grand Forks. Is it possible that some roads would still be closed with snow around then or should it be cleared by then. All suggestions welcome. Also we are not interested in large cities, prefer smaller out of the way places. We plan on stopping for a few days at the bad lands/Mt. Rushmore. Should add that we have about a week for the drive up.
