I didn't realize that a new thread had been started, apologies for the double post.
I went for a ride @ Stony yesterday and stopped by the track and several new loads of dirt had been dumped. When I went back today I saw that the loader had spread the dirt along your original layout, almost like a two track. After being there a while an employee stopped by (I think it was the loader operator) and was asking about the course because he couldn't envision it. I showed him the blue print and then asked if the park would be providing loader assistance on Saturday and he stated that he didn't believe so.
Below are some pics from today to save you a trip out there and to help you formulate a plan for build day. As of now it has the tight turns (2, 3 & 4) with an uphill to turn 5 layout. I am not sure if you decided to stick with that or not, but either way I think that a bobcat might be necessary, if that's even possible. Otherwise it might take more then a few build days to get it completed.
