Hi Sam,
Speaking of 1 mile tracks they are building one 20 minutes down the road from where I live in the middle of nowhere.
cant wait
I will have to it fit front brakes though there is a mallee forest at the end
If you want a look just google " south Australian timing association "
They are going well with only 40 members last year , now 60 members this year they have purchased the property aand had the all civils done, the track is all slurried up ready for sealing , they have the concrete barriers in place etc so just saving for the bituman.
They are doing a great job for a few blokes.
