My drum collecting began by acquiring a couple of vintage drum sets that I wish I had played back in the sixties. This began when I was about three years away from retiring, and thinking about how to spend my time. What has evolved is a ten year hobby that has finite limits. I had sufficient space for ten drum sets in the large house that we sold last year. Our new house has ample space for only eight sets. I stick to that number of vintage drum sets (no affection for anything newer than 1969), a few extra snares, all of my vintage A Zildjians that I have held on to since the mid 1950s through early 1970s, and a lot of older functional hardware. When I see a drum set that I want, I have to like it better than something that I already own if I want to acquire it. This is because my own house rules state that I must clear out one set before acquiring another one. I've been very fortunate that most of my drum sets came my way from trading something I own for the one I acquired.
My wife is very supportive of my hobby. I'm certainly no angel. But, I don't drink, don't golf, don't play with guns, don't do anything with motor vehicles except drive them, and have the routine maintenance on our two cars performed by professionals.
My wife of 46 years and I have a lot of together time compared to the thirty years before retirement when my job required much travel. My wife, my drums, our dog, and cooking keep me from getting bored. I have started to learn the game of disc golf because our 11,400 acre development has a championship disc golf course.
