Cooper, as has been said above, have a chat with our track day guru Steve. Believe you me, the committee are not out to urinate on anyone's parade, but liability and insurance are huge, HUGE potential issues that one cannot simply ignore. Do not assume insurance provided by the track covers an outside organiser - it simply isn't the case in every scenario. If someone has a big off and you were the organiser, you could be staring down the barrel of personal bankruptcy and years of litigation. The red tape and hoops to jump through are not there to spoil your fun, they're there to cover you with Teflon and ensure the safety of everyone.
It's why we've had to start adding the disclaimer to track day threads, membership forms, and the disclaimer in the magazine. If we didn't, and a member organises and promotes an inadequately insured track day on the forums that ends up with a lawsuit the member loses, the litigant could potentially come after the club AND every member in it - that's how serious it is.
Chat with Steve - it's a great idea and lovely to see the enthusiasm, but make sure a track day out doesn't turn into your never-ending nightmare.
