It's better than say an obsession with Micky's tail...just sayin
Mine is Disney, really pricey 1911s and lots of history books (love the eBay)!
Other than that I don't spend a lot, cars, housing, clothes, restaurants etc....
Okay.... I'm going have a hard time getting that picture out of my head.
I bought an e-reader (upgraded to a tablet) because I was going to have to build an addition to my house to hold all the books I just cannot resist buying as I wander through B&N with no plans to buy anything. I'm with you on the books.
