Don't know if this will help but my boss orders a truck of woodchips for the landing at certain jobs. costs $2/yard and gets a 100 yard load. on this particular landing it's damn near on the road and he wants it to look good for the people driving by. Anyways, we got the load delivered friday just before quitting time, he let it set there til saturday AM so that it frosted overnight, first thing saturday am while the frost is still on the ground he spread out the wood chips and told me that the wood chips will insulate the ground and the landing will stay hard for a long dang time. Also the woodchips make it nice for bucking logs and it looks real good too.
At the farm I work at the local landscaping companies come dump woodchips maybe you can find a way to get a load of woodchips free.
Now to get a little off topic, my buddy in the ADKS just got his property logged and they all called the landing the header. Confused me at first, dunno ifen its a north country thing or what. Anyone ever heard of that?
