I have, quite a few times. I have found rock hard surfaces and surfaces that are too soft for most aeroplanes. The softness of the surface is dependent on how recently it has rained and how much. All the ones I have seen where it is soft on the edges, landing in the middle would result in a bogged aeroplane.
If you can drag a wheel or both wheels or better still, the tailwheel then fly away you can look at the imprint on a second pass. I would highly recommend doing this in your own aeroplane only. Pilots who do this stuff in rental or company planes without specific permission and a reason are, in my opinion, a dangerous risk and dikheads.
The other question I always ask is why? If there is nothing to see, no good camping, nothing to do etc what is the point? If you are doing it because you may need to one day for real, forget it!
