I had a chat with Will about this yesterday on the phone.
At the moment we don't have enough people to make the event go ahead as planned (though we can pay more and have 2 drivers per team, and thus more track time). Therefore it would be wise to open the meeting to other people, just to make up the numbers.
However, if they are kart racers then there is a good chance they will be too fast for most of us non-karters, which will lower the fun for everyone else. One solution would be to put proper kart drivers with the slowest LFS drivers, to cancel out any advantages/disadvantages.
Also, if they aren't LFS players how are they going to join in and socialise. We'll all be there chatting away merrily, but non-LFS drivers will just stand in little groups and not be part of it. Thus I'd much rather have genuine LFS drivers, even if they are just demo racers. But if a non-LFS driver pretends to be a demo racer (i.e. signs up here, or does a couple of laps in the demo so he can vaguely chat about it), does that make it fair.
It's a dilemma if you ask me. We need more people, but the whole point of this is for the LFS community, not 'pro' karters who've never played LFS.
Perhaps we can have a few opinions on this? Can anyone pursuade someone else to go? There are no age restrictions, as long as you can reach the pedals.
