since they don't own the lands they ride on on, if you your asking if the LODGE has a age limit, NO not that I am aware of, its YOU that breaks down or gets to work harder on older sleds, IF your hiring a GUIDE off them, I again DON"T know of any age limit,a s your paying them for there TIME and experience, , less places you can get to or break downs, , THEY get paid the same
and I am NOT saying older sleds are NOT reliable or un able to get place
JUST a fact, age tends to increase the odds of a failure wear and tear and just time, has a way of making things fail!
as for WY and there rules, again, NO age limit on sleds, old enough one's MIGHT be able to get a discount on fee's, but have to be like 20+ yrs old I think on that
MOST folks traveling FAR< tend to rent over taking a chance on an older sled, two perks, in renting, 1 you end up on a new sled with the latest and greatest feature(or hope so)
and 2, you can beat on someone else machine, if it breaks, you get another one(if you damage it, you pay a fee however its NOT free)
NOW< down side of this, can be if there ALL out of rentals, bot if they have more NOT rented, , your's goes down, you get another one and keep your trip going and you riding
YOUR own sled goes down, your either again, RENTING< or paying to get parts and it fixed, and HOPE they have parts in stock to do so, to keep going!
there are age limits to how old you must be to ride and rent, but there the only age limits I know of!
