Yeah basically just show up about 830am and say Hi, after drivers briefing I'll call the officials to stand to one side to make sure we have enough to start the day, then you choose a corner you like the view from (if you like to take pictures, thats cool bring the camera) and we set you up with a seat, some shade, few drinks and food etc plus a radio. In front of your spot will be a chicane made up of orange cones which cars have to drive through (just like the ones on the video). If someone doesnt drive through it at all, or knocks a cone down just say on the radio "car number XX hit 2 cones" or "car number XX totally missed gate" and we apply a time penalty to that cars overall course time. If a cone is knocked down, it's great if you can stand it back up before the next car comes through to save a course car having to do it (as it takes the course car longer because it has to come from the start whereas you're sitting right there). Only one car on the course at a time so just as I will say it to the officials on the day i'll say it now, dont be afraid of picking up the cone if one gets knocked down, if you radio in "cone knocked down" you can also say "and im picking it up" - we wont let the next car go until we hear "cone fixed" or something similar to let us know you're off the track.
As many cold drinks and hot food as you'd like will be brought out at regular intervals, also if any officials want to swap corners thats easily done too (for example, you can do corner 1 first, then corner 4, then corner 7 or whatever one you like the view from) - I wouldnt expect someone to sit in the same spot all day (of course if you prefer that, thats perfectly cool), so I'd expect the officials do say 2 hours at one corner, then 2 at another etc.
It doesnt matter even if you only want to do it for the morning and not the afternoon, all help is appreciated and it's so simple to do - plus you get WAY better viewing than any normal spectator will ever get at this place
