The issue is not so much the lift as the terrain and permitting.
Troy's current permit limits him to 25 riders per day, all of whom have to have at least a current Avy I cert. Until and unless those requirements loosen or he sells some of his home sites, there's little upside for him in getting the cable spliced.
if i was troy, and i had the money, the ability to be able to take a 3 friends a day up would be all the upside i could ever need. if i didn't have that kind of money, why wouldn't i sell?
