It's another course!

The Burnside course is halfway down the 18th of the Championship and it has its own clubhouse.
The OOB to the left of the green has always been there since i first went in mid 1990s. It is quite far away from the green edge and did not really come into play in the wet conditions of 1999 and 2007. As it is dry it is now a lot closer.
From memory in the mid 1990s it was a large putting green just left of the 18th green by the boundary.
Another topic should be on the 3rd hole as it has been a different hole in 1999, 2007 and 2018.
Cheers
Ben
