I'm likely to be working on sat 19th, hoping to attend on Sunday 20th.
Suggest you contact one of the owners clubs and offer to help on their stand and display your bike in exchange for a free entry pass.
I have done this for the last 2 years with the DOC and for the peace of mind that your bike is in a safe place, it is worth it.
Thieving was rife last year on the friday and saturday nights, even in the exhibitors camping areas. We returned from the music marquee to find our tents had been searched, but nothing was missing because we had the foresight to get our helmets and leathers locked in a mate's van.
Apart from the scum element it was a great weekend, and there are always more bargains than you can possibly carry home. - another good reason to have mates with vans.
