There were a few women at some of the booths, but I didn't want to snag their pictures just to share them for all of you as my wife probably wouldn't appreciate a few of them. Yes, though, mostly men in attendance.
As for the camera, it was more operator issue than any thing else. I do t do well when. It gets warm and not only were demo rooms in the afternoon, but I was a bit overdressed and hot. So my sweaty hands would smudge the lens on my cell phone and since I was sneaking some photos, I wasn't good about cleaning the lens or even standing still to snap pbotos. Maybe next time I will take my DSLR and act like I am supposed to be taking pictures.
Oh, and it isn't that you aren't permitted to take photos, but sometimes people get upset if they just happen to be I your photo, and I just didn't want to look like some crazy fanboy of anything. Of course, looking back, nobody probably would have cared. LOL
