thanks andrew, as you can see the photo we will do our utmost best to rebuilt the track , it will totally different in size and surrounding , also the quality of the mud and jump.
Just one more advice, b4 lay the mud, u need to lay some drains( dewater pipes) in the lower place, otherwise the surface mud will be easy to wash away by rain.
U need to compact the mud layer by layer (10-15cm by a layer), then then track will be more long lasting.
If u dont mind, we can have more then 10 peoples come for test ride.
