Well, it was more than a thousand all told at the Denton, TX rally.
I was at the Tyler, Tx ‘Tea Party’ at 12-2:30. Then on to the Dallas ‘Tea Party’ by 6-9:30. They were both GREAT! I got pix but my computer has fierce pop-up blockers and cant upload any to FreeRepublic.
Went w/ my mom and husband in the afternoon and was able to bring the kids (15 and 4) to Dallas. AWESOME!!
I estimate it was at least 2.5 times that - at least! - and likely many more if you consider the continuously arriving and departing groups.
Here's how I figure that: the area where people were standing was just a bit over 2400 square yards.
You were there: folks were standing shoulder-to-shoulder over that whole area, but I conservatively (of course!) estimated an average of one person per square yard.
Ergo, 2400 absolute minimum, but I'd realistically say 3,000 - 3500 is much more likely.
The Denton police department was quoted by the infamously inaccurate Record-Chronicle as estimating 900 - 1000, but how would they know? Having spent the evening standing on the SE corner of the Square.
