A hobby is defined as "a pursuit outside one's regular occupation engaged in for relaxation" (Webster's Seventh).
I took up this hobby when I was in college. I am now in my early 50's. I have seen and played many pinball machines in this time and I like them all, from bagatelles to the modern day solid state machines. The set of games that I own reflects this as I have bagatelles dating from the early 1900's and pinball machines dating from the 1930's to the late 1980's.
I hope to share with you some of what makes this hobby fun and relaxing for me.
