HUGE development - I was down there today and now there is a GIANT hole maybe 2 or 3 car widths wide in the wall going into the olympia club below grade. I am thinking that it may have been an existing entrance covered up as there is a massive steel beam above the entrance and it doesn't look like the sides were disturbed to put it in, which makes it very interesting..
it's on the wall just above that silver car in the middle where those rust coloured lines intersect on the wall. I didn't have a camera with me or I would have taken a pic - thus using an old pic for reference.
