PA28 pilot reported failing to extend landing gear resulting in a prop strike.

Narrative:

A landing incident occurred while landing at ZZZ. Control tower was closed and two other aircraft were doing instrument approach work ILS's at the airport. The taxiway for runway 22L was closed for lighting upgrade and numerous vehicles were moving in the median beside the taxiway and several runway turnoffs were closed. I had a right seat passenger asking questions about lighting upgrade on the runway and talking about what a beautiful sunday afternoon it was. The landing approach was normal and as I started the flare the gear warning horn sounded and I immediately added full power. The aircraft settled and the prop struck the runway and bent approximately 2' on each blade. I made a normal go-around and put the gear down and landed. No damage to the aircraft at all; just bent prop blades that will require a new prop and engine prop strike inspection. The lesson to be learned as a retired airline captain is that no matter how many thousands of accident and incident free flying hours it only takes a second not staying focused for an incident like this to happen. This event has taught me a valuable lesson that I have already passed along to other members of my family who fly that if you lose your focus for a single moment this is what can happen. All distraction during a critical phase of flight should be eliminated if possible.
