It is used for making parking places on grass here, Sean.
You end up having something that looks like a lawn, but it firm enough to park on, even in wet season.
They are interlocking, so the whole area is like one unit.
"E pluribus, unum" kinda like!
As for the horses, I had one hell of a nice ride in the fog this morning with my best friend.
Going through the State forest and riding into my best mushroom spots to hunt for Boletes.
Didn't find any, it is a lousy mushroom year, this one.
Still, a lovely soft morning, with dew pearls on every leaf and needle, especially the young larch trees were fine, covered in spiderwebs and dew drops that sparkled when the sun broke through and hit them. Even saw a couple of the elk that have recently been showing up in these parts.
Then we let the horses out in the lower pasture and had a cup of coffee, a danish pastry and a long political discussion ( We are best buddies since we were kids, but about as far apart politically as me and the Jimster).
Somehow, after that, the maintenance cost of horses doesn't bother me much
