Just thought of another race night possibility, how about a rally cross style of racing similar to the UK, jumps, ripples strips, fake grass, whoops up sections, cobblestone sections, you could run both rally cars as well as normal offroad cars.

combine this with a 12th scale, mini every over fortnight, and a friday night tourer meet and you would have 2 decent size maeetings a week

I love the idea of offroad racing with no mess. and a consistent surface.
