No surprise here. NARM is intended to serve those with personal supporting memberships in over 1,000 participating museums, with those museums signing on to honor visiting family memberships as their own. AAM membership is for professional members in a professional context. I recall a bit of a row a few years ago when the fee for AAM retired members was changed, so as to not be considered and used as a "master pass" to other institutions. The rationale made sense then, and still does.
I'm impressed that Edison and Ford participates in NARM, and I hope you enjoyed your visit there anyway. Thank you for vacationing in our area - we can use all the support we can get after Hurricane Ian.
