I live in Cleveleys and had no idea a bmx track existed here. Where abouts is it?
There's the remains of a pretty cool DH track at Farleton Knott - there is suppose to be another one over the other side but I've not seen it.
There are some good DH tracks near Kentmere - a lot of it was a bit gnarly for me on my own with an xc helmet and no armour though! Some reasonable drops and it's all pretty tight through the trees. Couple of different lines. Looks well made.
