M, sorry to hear that you didn't have a wonderful experience at the show, I spent 7 day's there,set-up, the show and tear down, I didn't get to tour the show as much as I would have liked,I was busy at our booth, which I must say that we had very good responses from all visitors, and I wasn't rude once(thought about it). I did get the cold shoulder from some of the vendors when I got a chance to walk around, but I figured it my name tag. Did you get by the Velodyne booth and check out that $20,000 sub,rated at 8hz..It comes with software to program it, well I'm on the clock and the phones are ringin'back to tech supporting....Peace!!
