Are there any tracks that aren't tracks, that you can just pay to use? I mean like old airfields etc? I've seen that abingdon sometimes has trackdays, and I know that odiham do as well.

I've seen the MCN vids among others, and they all seem to use places that are set up to ride on without being 'proper tracks'

Looking for a cheaper alternative to organised events to build up some skills...

It might be that they cost just as much, but if you don't ask etc.....
