"Shimrod and Bill are safe in a well-defined zone of solid reality,..."

Well defined? I thought there was lots of work still to do on that? *grin*

THEN we can see what's up with anecdotes about semi-solid reality and vague, amorphous reality. (Like the math professor I knew who said he wanted to drop some acid and make breakthroughs in topology).

I dunno how safe I am, but walking on other people's clouds seems risky to me.
