There's a North of Scotland Kart Club just south west of Golspie (http://www.nskc.co.uk) - search on google maps for golspie golf club, and then head south.
Rather than someone doing everything for you, have a try yourself.
I know the hardest part is getting the layout mapped out, so I've started the track for you, by laying out cones to show where the track borders are.
The layout is to scale, as you'll see from the image.
Have a go at finishing it off by putting chalk, barriers, speed humps, etc, (or any combination thereof) just to the outside and inside of the cones, then remove the cones.
Entirely up to you if you want to share your layout.
However, I would suggest that if you are asking the community to make something for you, then it's only good manners / fair that you are prepared to share too.
Having a look at the track again, and assuming that, like a proper small track, there was only the single start point, there was no crossing junctions in more than one direction, that you only drove one way on the track (ie no oncoming traffic), and that no reverse configurations were used, then it looks like there is about 12 different track configuration permutations available.
So.
Do you just make an open play layout, which allows people to drive where they want, with the potential consequence of meeting another car head on, or do you make a dozen layouts with, as in real life, cones on the bits of track you don't want drivers to use for that particular configuration?
could the Blackwood car park be a better option for the layout?
It just seems like that section of the autocross area makes it pretty small. It may not be to scale, but the layout on the car park might be bigger perhaps.
Couple of layouts based on the main Golspie layout, as named and used by Caithness Car Club - Kylestrome and Littleferry, along with a layout just using the perimeter part of the track.
