Hank,

My issue with you is that you write as though the info you posted is "the" answer, when in fact you haven't an f'n clue. It could be the best alternative, or it might be a really stupid one. Either way, you still don't have a clue. If you were a smart guy, you'd know that even copy/paste expertise if quite often worth even less than the zero you pay for it.

The smartest people I know are typically the first to admit the limitations of their knowledge and expertise. Know-it-alls are occasionally correct, but it appears to be more a matter of coincidence than design. The fact is that no one on this forum, including you, knows whether the sand berms are a great alternative or a really stupid one. Why get wrapped up in solutions when you're clueless as to their efficacy?
