On your way from Gauteng to the Free State or Cape, pull into this refreshment stop and quickly hop out and find the cache. Park in the shade in the parking area about 20 meter from ground zero (GZ) and go get it. Replacing the cache in exactly the position as found will ensure its survival.
Note that this cache can only be reached from the south bound N1 freeway.
This is a very high muggle area due to the restaurant nearby, but strolling around will ensure that you do not arouse any suspision.
