In the few videos I've watched, they tamp/compact the gravel, but
not the sand that is layed over the gravel.
In my test fit, I'm using about 2" of sand over solid shale. viz:
A local playground is being re-done and there are piles and piles
of sand there for the taking.
Problem (?) is that it is damp and I do not know how that goes
What I'm finding is that I can hand-tamp a 2" layer of the stuff
down almost 1/4".
Don't have any dry sand to compare with, but I'm wondering if the
tampability is due to the dampness, or is that just the way it is
with all sand.
I'm thinking settling over the years...
Bottom Line: Am I asking for trouble if I chince out and use the
free (damp) sand? Or should I pony up the cash and buy some dry
