Thanks guys.
We actually went and played on Sunday also. My son played the first 9 holes and then putted only on the last nine as he was pretty "golfed out" at that point and I didn't want to push him.
There were 3 of us playing, a buddy of mine joined us and my brother in-law dropped out at the last minute. So there was a guy at the club who was by himself and looking to join up with a group. Normally I don't mind but our last exerience with doing so a week ago wasn't very pleasant, so we tried to discourage the guy but he really wanted to tag along...so we said "ok".
The guy was 60 years old and just crushed his drives dead striaight and about 300 yards, his approach shots seemed to be laser guided and his putting was incredible. By the 9th hole I look at the scorecard and realise he was 1 over par, at which point I asked him what his handicap was and he replied "These days I play off about a...4." I looked at my buddy and we both sort of looked at each other with a "Okay...THAT explains it".
What a great guy too....totally unpretentious, didn't try and coach the rest of us unless we asked for a tip, he really encouraged my son (as did my buddy) and was a true pleasure to play with. In fact it was an honour playing with someone who was that good. He shot a 74 for the round.
