On hole 6 at Royal St. George, if you hit past the hole and get a view back towards the tee box, there appears to be a chair sitting on top of a hill beyond the front of the green. Any ideas what it is or, if it's a chair, why it's there ?
It's a bench. For people to sit on. :-)
IMHO it's a bench positioned at a tee, probably at #4 or #5.
