Thanks again to all. I will continue training like hell every day. Actually have already started. Also read that some athletes do indeed use a straw to train their lungs for high altitude. Others dose up with ginkgo bilabo or sumsuch. I've hiked up in the rockies a bunch, but that was years ago when I had time (read, no kids) to wait out the altitude change. If yall can pass on any tricks, please do so. However, I'm ready for the fact that it's just something to be pleasantly suffered. Great forum.
