This post however shows a photo - but I do not remember when.
I vaguely remember it was in the late 90's as I happened to be at Ardmore a couple of days after. We had a Cessna 421 having an interior update at Aerotrim and I believe the 748 was taxing there as well for some interior work when it for some reason taxied off the taxiway onto the grass and over a drain which collapsed. There was a video floating around of it actually happening.

Just read the comment posted. Pretty sure it was the 80's, late 80's, and the visit was fog related. It definitely happened on a Sunday afternoon.
