Personally I think that FC have got what they wanted – car park packed full to bursting the few times I've been.
I think the trail is OK for youngsters – my youngest loved it (8 years old) but has moved on to slightly harder stuff now.
My favoutite 2 bits are those snaking through the trees (christened 'Narnia' and 'Back of the Wardrobe' by my kids). Mind you, we rode them in an extended dry period, I could imagine they're a claggy nightmare now it's wet.
May visit again when it's dry again but it's 60 miles for us so we'd have to really be doing something else as well such as GoApe.
