Rode round Gisburn on Sunday, following the red signs and taking (whereever possible) the more interesting option. So for example we did the teflon rollercoaster.
There was one section where there were two options. It was quite short and followed a little climb that involved going over some biggish stones. The two options were basically round the side (looked a bit bermed) or over the top which led to a short steep smooth drop which turned right slightly at the bottom and then inti a left hand berm (where it met the other option I think)
Was that short steep smooth drop 'the slab'? If it was, then it was smoother than I remember from pictures on here (that I can't find anymore). If it wasn't, how did I miss it?
If it helps locate the bit I'm talking about, following it we went down a bit, then up a bit and then a chap who seemed to know the place told us we were at the highest point on the route. It was before the teflon rollercoaster.
