To fish a fly rod in a holder next to casting rod running plugs? Wrong or not, its been a couple years since I've gotten out for winter steel so thought I'd post a fishless report. Had an invite to drift a local river with a gear buddy from work. No steelhead for either of us but I did manage to swing up a sucker from a fishy looking seam further downriver. I tried my 10wt rigged with a sinking head in the rod holder, mostly as a goofy experiment to see how it fished through plug pulling water. No grabs for either rod but it seemed to fish surprisingly well. Getting down was not a problem, since I had to switch to unweighted flies after donating a couple to the bottom. I've had plenty of grabs on the hang in the past, so I don't see why it wouldn't work. Not counting it as fly fishing by any means, but that won't stop me from running a fly if he wants to drag plugs for spring Chinook in a month or two. At least felt like I was fishing. Very cold but beautiful day. Thankfully we started to thaw out late in the afternoon, not far above the takeout. Always good to get out.
