Listening to a couple of "pilots?", talking to each other over the Great Salt Lake (GSL). They were talking about "targets" and Fremont Island, among other things. Sounds like aerial surveillance, but at 05:00 in the morning, I don't see how or what they are able to see. They were on 132.525, then switched over to 134.075 as they headed west. I have heard these guys in the past, but on other freqs. Normally early in the morning.
