"Is the point that they skied every resorts in the state in one day? Then they're in the company of Indiana, North Carolina, Alabama, Rhode Island, Iowa, Ohio, Connecticut, New Jersey, South Dakota, Virginia, Maryland and probably a few others. I don't get it."
??Most of those states don't even have a series of legitimate resorts. I grew up in NJ and they have 2 actual resorts and maybe 1 or 2 other local ski hill/clubs. I'm pretty sure Virginia, Maryland, RI, NC and Connecticut don't have more than a handful of resorts either. Not to mention that a lot of the states you mention are tiny in comparison to UT. It would take about an hour to get around to NJ's resorts. In UT, it's about 5 hours from Brian Head to Salt Lake and another hour north to Snowbasin/Powder and then another hour north to Beaver Creek. That's not really taking traffic into consideration. I'm not understanding the comparison- oranges with apples.
I don't think it's supposed to be a jaw-dropper, but if you think about the time and effort it takes not just to drive, but to gear up, walk to the lifts, ride up and take a run it's an interesting idea. In this case, you have 7 + hours of hard driving, plus another hour or two + of driving/commuting between resorts and then what 20-30 minutes minimum at thirteen resorts, so 4-5 hours or so. That's all pretty conservative and I bet it would take significantly longer when actually performed. So not impossible or amazing, but noteworthy.
