yeah, would be best to post the disclaimer up somewhere. Sorry, I dont mean to doubt things, it all sounds really good, but is a disclaimer really worth the paper it's written on? Don't you need proper insurance if people are paying to ride there? I'm not saying I want it to cost more, I'm all for the "do it at your own risk" but it is legit doing it this way right?
Oh, and big up the speed trials, that sounds mega!!
