How about a solvent resistant balloon filled with WD-40? Eh? Or jug fishing with marker bouys. Looks like you have half-dozen spots marked until they bob and start to swim away. Chasing them is great fun. An 8 pound striper has no troulbe pulling under an empty 20oz water bottle. Then when he pops back up the chase is on again.

Beside, the biggest most well-kept secret is still available online. So super secret, no body will talk. You even have to do it at night. Makes others Green with envy until they too see the light!
