Cruising the freeway this weekend when I get a couple of KA blips as I am starting to climb a slight hill. Slow quickly as I am thinking it might be I/O. Alert gets steady and stronger as I crest the hill(bogey alert 1) I see about a mile away a highway patrol with a truck pulled over. I'm thinking this is where the alert is coming from. I pass the highway patrol and truck but STILL getting forward arrow with the alert maxed out so I keep an even speed. Sure enough about another mile later there is a sherriff cruising toward me with his KA on. Without the foward arrow I would have assumed the alert was coming from the first LEO who didn't even have his radar on!
