Good thread, Mike.
There is nothing that compares to Barnbougle.
On the last day of a gof trip in April we were happy to just play 20 on sore feet. After the round and a bit to eat, we had to play more. We headed off the the pro shop, handed over $35 and headed off for another 20. After a couple of beers, we were lured out for another 9. By this stage the golf was free and we had to get in as much as we could.
In the end, that day we played 49 holes on a top 50 course for a little over US$100. And no further obligations.
Surely there is nothing in the world that comes close.
