Recently retired from the military and Fed Government. Am bored stiff, suggestions on what to do?

I spent 31 yrs in military, to include reserves, and additional 20 yrs in Federal Government service. Its been a year, and I can't find anything to occupy all my time. I used to work 10 hr days, although paid for only 8. Not permitted to do computer work for any company for 2 yrs and I might be deceased by then? Don't want to greet people at Wal-Mart, or volunteer at a library. Reside in very small town of 18,000 in cold climate area. Over-did my 3 hobby's and got bored and have problems sleeping because of my nasty habits I picked up since retirement. Any good suggestions for a "small-town" former military boy in fair physical shape except for war-injured leg. Serious advise only - please.
