You really ought to be more careful in your characterization of others words, Mr. 533. I didn't advocate leaving the dams or unplugging them because natural rivers are "scary" but because the advantages of two large reservoirs and flood control were worth more than the restoration of "natural" rivers. We dodged a bullet with the recent drought, but the glaciers are retreating and we will likely face the threat of massive fires again, sooner than later. What will you do when you turn on your tap and nothing comes out, or your house is on fire and the firetruck has no water to pump? And you impugn MY maturity? It is you that are not thinking like an adult.
