I was lucky enough to be in Las Vegas during PMA last year and wrote up a traditional roundup here, but not this year. Maybe some of our Nevada APUG types or someone who's planning on attending can do it this year.
I just realized you wrote PSA. Did you mean PMA--The Photo Marketing Association show where they introduce all the new gizmos?
A PSA is Prostate Specific Antigen....when you guys get older you'll understand more about it :}....If the PSA levels increase in a blood test then there is a risk of Prostate Cancer...however, this is the APUG, not my medical office....back to the dark room.....:}
