Sand is In!
Apart from the fact that my friends and I are going on annual trips to the environs of “Sandy Lake” in Ontario, or that all the natural gas/oil “fracking” (causing and keeping open miniscule underground fissures) consumes a lot of fine sand to keep the underground rock fissures open, or its use in producing cement mix than can be troweled into smooth surfaces, or in the playground of your children or grandchildren, sand is one of those natural things that are truly plentiful and -- amazing.
