Well said Roy. Too many shows (cars and bikes) are being hijacked by the mobile phone covers, sweets, boot Polish and the tool that does it all for £30 type traders. I couldn't get near to anything last year within an hour of arriving.
I can recommend the Kempton Park shows, worth £6 entry fee and always a great show outside in the car park with so many riders bikes to look at. Not much Japanese stuff but there are normally a few traders selling gaskets and a few nos parts so some bargains to be had.
