Reminds me of when I was out with the ladds and I went over a 'moist' bridge going over a railway, it was made of wood and it had been built ages ago so when it gets wet it's slippy as chuff!!
Anyways I was going over it about 25-30MPH and I could feel the back wheel spinning when I revved it, so I revved it some more to keep the wheel spinning (to look cool as we all do) and anyways the bike spun me out (didn't spin out from underneath me, just kinda drifted me into a 180) so non the less I was facing the way I got on the bridge and I thought what the hell... Turned the bike another 180 and carried on up the trail on my merry way
