Hex'n....or not

I took a drive a week or so ago in hopes of finding some hex activity and the girthy fish that go along with them. I arrived streamside, waited and waited and waited and saw exactly 7 bugs fly by. Not a single fish showed. I tied on a big rubber legged ugly and pitched down and across on the walk out...I hooked a head shaker but it popped and then I saved the night with this guy...
Where the hell are the hexes?
