Sunday's event was not a march  organizers say  but a rally  beginning at 10 a.m. local time inside  the Sam Boyd Stadium in Las Vegas . Officials tell Fadel that although the venue can hold 40 000  they expected roughly 17 000. The organizers say they are less concerned with crowd size than with spreading their message. Nearly two hours after doors opened  Fadel estimated that thousands â many in the movement's trademark pussyhats â had filed into  the stadium  under clear skies.

Q: "This is a game changer " says  Thomas Garrison  an archaeologist at Ithaca College who is one of the leaders of the project . It changes "the base level at which we do Maya archaeology."
The data reveals that the area was three or four times more densely populated than originally thought. "I mean  we're talking about millions of people  conservatively " says  Garrison . "Probably more than 10 million people."
The researchers fired LiDAR technology  short for "Light Detection and Ranging " down at the dense forest from an airplane. This research was organized by the PACUNAM LiDAR Initiative  and  Garrison  says the area's size is "more than double any other survey that's been done with this technology."
"As it flies the laser pulses hundreds of thousands of times per second "  Garrison  adds. "And every time one of those lasers hits a point of resistance it stops and sends back a measurement to the plane."

LiDAR allows scientists to accomplish years or even decades worth of mapping in a single afternoon. For example   Garrison  says  he  was part of a team that worked for some eight years to map less than a square mile at a site called El Zotz. The plane using LiDAR took data for 67 square miles in a matter of hours.
"It's very humbling " says  Garrison . "For those of us that spent our lives mapping and slogging around this area ... you just sort of have to bow before the LiDAR and accept the fact that it's better than you are."
The team surveyed 10 separate areas. It took months to process the data. As the picture became clearer   Garrison  said  he  would sent emails to  his  colleagues expressing surprise at the magnitude.
 He  recalls seeing an initial image of one area in northern Guatemala. "I saw this image and I said  the whole area is covered in Maya settlement. You won't believe it "  he  adds. "And then once we got the actual data and saw the whole scope of it. We said  'Wow  we're going to be able to really do something with this.'"

Q: I sit here writing a letter that I never thought Iâd have to write. On Feb. 13  my husband and Graceâs dad   Paul Bauer   was violently taken from us. Needless to say  our hearts are broken in a million pieces  and our lives are forever changed. But thatâs not the reason I am writing.
 Paul  would have been terribly upset that  he  inconvenienced so many people with the parking restrictions in our beloved Bridgeport.  He  would have winced at the thought that the Dan Ryan closed down for the funeral procession.  He  never wanted to be in the spotlight.  He  never thought of  himself   only others.
I want to thank those of you who waited for hours in the cold to attend  his  wake and funeral. You have no idea how much that meant to us.
I knew  Paul Bauer   and  he  was as wonderful as people are saying Â»
Hundreds gather at Bridgeport church for Cmdr.  Paul Bauer 's wake Â»
