I got a little carried away with the Roger Dean collection, but figure it's better than chasing floozies and getting into bar room fights, lol. Had enough of that back in college..
Collecting also has an investment side, and 'collecting' stocks is fun and interesting, though lately the S+P 500 has been the main stock vehicle.
Btw, some of the vinyl albums listed have done amazingly well as investments. One that cost $22 is now worth ~ $300, and many have doubled/tripled. But mainly I just like the artwork and the music.
