Litter on the park trails

My Better Half and I hiked part of Devil's Lake and Parfrey's Glen as a belated 35'th anniversary celebration. Part of the path by the lake is asphalt and wheelchair accessible, but after a very short distance there's no chance of getting a wheelchair through.

I wondered if it would make sense to rent a litter so that friends of a wheelchair-bound person could bring them along. You'd need a team of 3, more likely 4, as a minimum, and some way to retrieve people if a carrier sprains something along the way.

Wikipedia says these are used for tourists in the Huangshan Mountains, so there's some precedent--though there the pros carry people. Liability issues would preclude that here.

Some of those steps are pretty steep.
