Wow, lotsa HEAVY stuff and other things over which to ponder....C'paw, I read with great interest where you consider yourself "an aging 60's radical", and here I thought you were just knocking on 50's door! 'Course just cause I was born in the same year as you don't make me a 60's radical, I still will only admit to 50!! And what is that about the Birch John Society? Are you interested in the preservation of wooden toilets?
