Being mostly retired I looked into hobbies. Golf, tennis, bowling, billiards and many others all have expensive entry fees and expensive participation fees. Then I found the hobby with zero start up expense and zero participation expense. It actually pays me to participate. Find veterans and thank them for serving. Today, among others, I visited with a nice gentleman, 86 years young, who enlisted in 1946 and served through 1974. The best payback is often when a spouse is with them. The smiles and the handshakes are a great reward. It's a great new hobby that can be enjoyed anywhere.
