I have done a couple of additions and improvements. I wish I had the room to do something grand like Stav., but what I lack in over-all size, I try to compensate for in technique.

I needed a 'wide open, go for broke' jump so I added another landing to make a triple.(I know it isn't really wide open, but it's as close as I can get on my postage stamp)

I made some pretty abrupt elevation changes on the hairpin, and carved some 'character' into the track surface.

I added a bypass around the curved jump/chicane. But I carved some grooves and made some lumps to make it 'interesting' to take under throttle.

I have added some more gypsum pellets to the soil in a couple of areas that needed it, and reworked the 'big berm' a little bit for drainage. When it is watered and swept, it is a tacky blue groove type surface. When it is dry and dusty, it is like driving on 2 inches of fresh snow on an empty parking lot with a camaro.
One of the sad benefits of having such a small track is that I don't get enough velocity built up to actually break many parts, but there are enough challenges on the track that no 2 laps are the same. I have hours of fun out there...But you know how it is...The track always looks better on the other side of the fence[8D].
