The plot thickens. 65 clams is pittance as an admittance fee if you're Big City, sports fanatic, or really into something, and money is no object. But rjdankert you do make an excellent point: 20 curious folks forking over $65 for a couple of hours of enlightenment can generate serious coins ($1300!) for the instigator of an axe course who proffers to be doing this as a public service/hobby a few nights a week, and also happens to have on hand a cache of 'unspoken for' products for sale in the backroom.
Then again room rental is skyhigh in New York and likely so (but in reverse) is public interest in old tools there, so I've also got to go with 'benefit of the doubt' about motive, every now and again, too.
