Just washed/waxed my truck this weekend before the road salt starts. First full hand wash since April. I hand wash twice a year (Spring and Fall) and usually wax it since I put the time in to wash it. In between I just power-wash it to get the mud/dust/dirt/salt off as needed.
Anyway, the front end and the amount of elbow grease I had to put in to get it clean suggests there were plenty of bugs this year, somewhere, at some point.
That said, anecdotally, I didn’t do much hatch chasing this year, but I’ll agree I mainly struck out too. Had one decent night on The Pine, Sulphurs and Slate Drakes. Not great by any stretch, but everybody in our group caught fish that night, on top. Had one skunking each with no appreciable bugs (I didn’t feel like nymphing, and just relaxed on the bank mostly) on Kettle, First Fork, and Penns. Others who were nymphing around me those evenings were catching the occasional fish, but it was slow all around. All late May/early June timeframe. Too small and varied locations of a sample size to make any determinations off of, but FWIW.
