I too have had a similar experience observing a guy adapt to an awkward casting situation. He was fishing from a concrete "wing-wall" about 12 inches wide, that ran perpendicular to the channel he was fishing for redfish. He was a right-handed caster and there was a six foot chainlink fence alongside the wing-wall to his right, hampering his ability to make a decent cast. He simply turned around, facing away from the channel and started casting, releasing his fly on the back cast, putting it where he wanted it every time.
