I believe Mr. Skagfeld will have something to contribute here once he gets his fat arse out of bed this morning.
I remember my FIRST Grizzly ride, at Borden, too well... in the back, closed down, on the dunes (before the greenies turned the world half-mad and shut the place down - a whole other topic*). I was well hung-over after a typical light night in the mess and my driver was a psychotic MCPL whose eyes pointed off in different directions at any given time and whose grin just got wider with every ... er ... groan coming from behind him...
*Y'know, back when you could dig there, and squat in the woods...
