HI Thomas its not far, you would take the M65 motorway from the Junction with the M6 motorway and then head towards Blackburn & Darwen then consult the map that Scot Cat has shown you. BTW, There is another fish auction very near you this Sunday, it is being held by the P.D.A.S. (Preston) and it is being held at the Leyland Motors social club (I think thats what its called, but its the one with the cricket pitch) in Leyland. But I can't say for sure if there will be any Scleromystax barbatus for sale.
thnak you i am going to the auction at leyland on sunday thomas
