2014 USA Science and Engineering Festival USASEF in Washington DC - Wow

You can read where scientists, engineers and technicians write about how we need to excite more kids about science and engineering. Engineering and science companies, government agencies, universities and primary education institutions all understand that we need to excite more people about the science and engineering disciplines.  Some of these groups worked together to create the USA Science and Engineering Festival in DC  and associated events in other places.  This was a big (big big) trade show like event with hundreds of companies probably 50-100 universities and dozens of government agencies.  Several of the universities had multiple booths in different sections for their various colleges, programs and labs.  The event filled two floors of the Washington DC convention center.  Six stages ran presentations and talks continuously during the event. The kids and older folks who are still kids at heart had a great time. The USA Science & Engineering Festival is a national g
