I have been in the golf business for nearly 30 years and it's pretty rare for somebody at a country club to actually throw a club.
But many years ago, a member's kid threw his driver in a pond after a bad tee shot. The kid was always a little doosh and he lied to me and said it slipped but one of my co-workers said he saw him throw it on purpose.
I had to get our row boat and go out on the pond and look for it. He was pretty fortunate that soon after I got out on the boat, I could see the club shining down about 5 feet below the surface. All I had to do was to slide off the boat, and dive down to get it.
Unfortunately for him, as previously mentioned, he was a little doosh...
the club is probably still there.
