Hunger for rock eating up supply of sand, gravel

Hunger for rock eating up supply of sand, gravel, Seattle Times, Jan. 13, 2008. A resource many of us generally don't think about much...

When I was preparing for my exam in Land Use Planning, Dean Spencer said that class could be summed up by two principles: (1) "It depends." And (2) "The gravel pit always loses." (See, one can retain important information from a class taken 27 years ago! I also remember Prof. Haar saying that zoning was like a quart of milk and a comprehensive plan is like a cow.)
