My youngest son,40, cherishes the vinyl I collected in the military.
Surprisingly, like Baseball cards, they're actually worth a few dollars now!
I had a very close friend in Milwaukee that used to make a very good living making square plates of carbon fiber for the severe audiophiles, wealthy ones, in Japan to set their turntables on. Also small triangles to put the plates on too! Some had concrete footings poured for the set-up to be placed on. BIG BUCKS!
