Only thing I had go after a fly was a big dragonfly that attacked my fly while it was dangling from the rod. But I've had several weird encounters with lures while bass fishing. The weirdest was when I was fishing at night with a Jitterbug, a big surface lure. It was a dark night, and I'd cast and listen for the lure to hit the water (rather than the bankside brush), then listen as I retrieved it across the surface, because unless the sky angle was just right I couldn't see much on the water surface. I was listening to the lure come across the surface when I heard a rather soft splash at the lure. A strike. I set the hooks and suddenly I could feel my line rising into the air! My fishing partner asked, "Got one?" I said, "Yes...but I think it's flying!" It put up a pretty good aerial fight for a bit, and then I got it directly overhead where I could see it against the sky. It was a great horned owl! It swooped close to my partner's head, and he covered his head and shouted, "For God's sake, stop reeling!" He grabbed a flashlight so we could see, and I finally jerked the rod hard sideways and down, and brought the big bird down on the water, where it floated on its back, taking its free foot and trying to scrape the lure off its other foot. I was wondering just how I was going to get the vicious looking bird unhooked when, fortunately, it got itself free and flapped toward the bank. The last we saw of it in the flashlight beam, it was standing on the bank glowering back at us.
