The meet is held on the first Wednesday of every month and can attract 2000 bikes and 3000 people. Get there at 6.30pm and it can go on until 11pm.

The original meet was the Lord Derby pub situated in the side road but popularity has meant that bikes are now parked all along the 1/2 mile of dual carriageway.

The meet really is spectacular, if only by it's size and always has police in full attendance. Even so, you can get away with sparky knee downs around the roundabout and as long as you don't come off, then the police will just stand by and watch. I even managed a small minger past a bike cop who just sat there and shook his head!
