Warren,
Nice picture and thanks for explaining the puddle. We have them too, except ours are filled with about 2" of fine dust. It would take at least 4" of good rain just to get the dust wet down to the ground around here. And the more fires we have the worst it is getting. Water has now became as important as gas here in this area as we are just flat starting to run out. I have seen it bad here before, but with all the increased demand from Southern Calif., for more and more when there isn't any, it is going down hill fast and the first lawsuits are already being filed.
