I joined the Navy at 17,(1960) and retired with 22 1/2 yrs. I then opened a small engine shop, then went to college, after that I opened an appliance /AC shop. The I started to work for the county as a traffic signal tech and retired from there with the highest level for that, I then worked privately and installed /maintained Traffic Signals all over the SE. Now at 72 We own a small farm and raise livestock, I have never had time to get bored, and to make sure I am not doing a course in gunsmithing.. I have never been bored and I do love my retirement as I can take a day off (or several) when I want.
