The lads I ride with used to ride Nannerch before they bulldozed it.
You probably are nearer to Wiswell near Clitheroe
(I think it might be nearest to Sabden?). Great track nice surroundings.
I'm rubbish with directions, I tend to follow someone myself. We were talking about visiting Mac Forest in the near future , I'll let you know when we are going. My 10 year old son has just got a new Giant mtb so I hope to take him up to Rivington and do an easy loop quite soon. There are some nice riding spots in the north west but you only find out about them by getting talking to people on the trails.
There are also some amazing bikes on this site, I havent seen a picture of a Klein Attitude for years, that was the bike I always wanted but could never hope to afford. I think one day I will tho
