I suppose you could say that about a museum too.
I still can't fathom the objection to the HOF. It's not like it's any skin off your backs. If it in anyway helps bring visitors to the museum it's a good thing, along with acknowledging the pioneers that help create, build, maintain and hiked the trail. Don't you think Benton MacKaye and Myron Avery deserve such recognition?
It could very well inspire someone that has nothing better to do to step up and do something extraordinary for the trail, which wouldn't be much different than an attempted thru-hike, the later considered a selfish endeavor.
