So sorry you had a bad experience but, Museum is a building housing collections of items - not necessarily old or antique. Living artisans often display their works in museums.
Before your next visit you might want to check to see what they have on display before you make the trip.
I too am a senior citizen who appreciates hand quilting and older methods of quilting. But I've also come to love all the new fangled "goodies" available to us today. I wouldn't dream of making a quilt with my rotary cutter and cutting mat.
