Wow. Ignoring the "historical" (I'm assuming you mean fossil) record, and the difference between species diversity and success for a single species... ...can you really write this on a site mostly dedicated to a group of fish that require cold water? Really? No. I said historical record...

Any policy we do make should probably be, for our own good, to do nothing. The historical record shows pretty clearly that most species, especialy humans, do better during warm periods as opposed to colder ones. The only problem, really, would that you might run into Beetle - wearing a thong.

FWIW, your boys are tougher than most adult males I know. Great stuff, trip of a lifetime.

I'm going to build one of these this winter: Spira International Inc - Mackinaw Drift Boat .
