I'm a retired Police Captain with the Metro Nashville Police Department . I have trained law enforcement and corrections across the U.S. and Europe (notably England, N.Ireland, Germany) in high risk offender control, dynamic control simulation (full contact training simulations without injury), personal protection, SWAT operations, weapon retention/recovery, and knife defense.

The photo above is one I took of a house I built in 1978. It is two miles off Whites Creek Pike in Joelton (Nashville) at 4120 Baxter Road. It has 5 bedrooms, 3 baths (one with a sunken tub) and cost almost nothing to heat or cool ($60-$70/month). Large dome (32 feet diameter 3/8 sphere) is made out of plywood (now covered with shingles). Smaller dome (24 foot diameter 1/2 sphere) is made out of sprayed concrete with rebar and 6x6 metal mesh about six inches thick. I was flying a Cessna by one day and leaned out and snapped a photo. You should have seen me trying to get financing to build this thing from my blueprints..."Who's gonna build it."..."I am"..."Have you ever built one before"..."No"...
