I was there, and I've been to some real cattle drives on the Mall over the years. They'd be doing well if they had 100K, teh 750K number must be a nationwide delusion. The photos from the Free Republic site tellteh story.
We had approximately 2000-2500 at SAS/AIMM. We were much better behaved than some of teh 'mommies' and the SAS women were far more attractive (smarter is a given).
