Oh great. Look for the new wave of illegal immigrants using this border-crossing route now that it was publicized. Before long they’ll taking jobs from American zamboni drivers.
The Ice Climb would make a nifty citizenship requirement. I am 100% in favor of granting any illegal alien who survived the climb a probational green card good for 60 days. It would of course be renewable by sliding down on a Flexible Flyer, and re-ascending.
