there is a strip in caroni, not sure how long it was. Its south of fredrick settlement, and no its not part of the abandoned horsetrack, i went there about 2 yrs ago, its a bit narrow for adding a return lane, it was hell to get to though, we had to use the 4wd range to get there.
i'd doubt that the farmers would like us using it though.
it was a bit weird to see this paved runway in the middle of the bush, it looked like it was used for small planes.
Probably someone knows of somewhere else like this one.
