For a discretionary activity, everything that makes it harder to participate decreases likelihood of participation. Now the geniuses running AMA think that it's a good idea to INCREASE the obstacles for a kid, in the form of charging for something that heretofore was free. Did none of these guys ever take a 100 level economics course?
And some say it's about insurance? BS! In 2018, per their own IRS filings, AMA spent $1.2 million on ALL insurance. That's flying, for staff, for slips trips and falls, buildings, etc. I seriously doubt that 50,000 free members cost AMA $750K to insure.
