Okay, in the back of my mind I thought maybe the someone had remembered his birthday wrong.
I was correct, the guy was not 83 but 81 years old. I confirmed this with several other golfers whom I hitched a round with the other day. Their 4th had back issue and I was walking on with the last minute decision.
So apparently, these 3 golfers played with the same guy in the past and one of them played college baseball one played college football, one played high school football. The one played the college baseball asked if I had played with the same guy there at the golf course, of course, I replied yes and shared our story.
His comment was, "okay , when he started playing well, I thought this will blow over soon but he kept coming up with pars and birdies and beat the crap out of us... later walked in the 19th hole and the bartender asked the 81 year old - the usual Mr......and he said sure and get my buddies a beer" as they walked in after the 81 year old.
So my mistake, the golfer is 81 instead of 83.
