You do NOT need a fly rod, to fly fish. I've used a spinning rod, with GREAT success for decades now.
Just tie your main line, to a
torpedo bobber (see pic below).
Then tie on 4 feet of leader. Three feet down the leader, crimp on a BB sized split shot. Then, at the end of your leader tie on an Olive Green, or Black, Woolly Bugger or Teeny Nymph. BAM! FISH ON!
Woolly Bugger:
You can get all of those items, for cheap, at Bi-Mart. The trick to this "fly/spin gear" method, is to think SLOW. Then, go even SLOWER.
X 2 on all of the other ideas too. Or, just slow troll with a couple of split shot--and a 1/2 worm on your hook. Easy peasy.
