Hey John, I am glad to see that you are getting out on a bike again. Although I suspect that the pics are of you're mate, or you havent half changed mate!!
I went up there a couple of years ago with some of us on BMX and some on MTB, we found a bit of a downhill race track, which was great, until the mass pile up at the end.
We also seen some kids on jump bikes, going over 6 foot high mud ramps, and doing 360's over them, no fear at all. We were all stunned.
I have some photos of that day, I will post them later.
