I mentioned golf earlier as have many others. Today I got a good look at the demographic at a local course. The siren went off part way through our round due to lightening and everyone had to leave the course until it was safe.
We ended up in the restaurant with around 60 people. I'm 55 and my friend is 54. We think there were only 3 or 4 golfers younger than us, and at least 20 of them were well into their 70's. No one under 40 at all. Now, a part of that could be because it was a weekday, but the lack of young people taking up the game must be cause for concern to clubs trying to pay the bills.
