I know were my uncle docks his boat all the boat owners leave some eel/bait traps hanging off the dock and no one bothers them.. people at marinas usually leave that stuff alone....and if you know someone who lives on there boat you could have them keep an eye on them.
Just my .02
Good luck!
I like catching them big American Eels on ultra light tackle on Clam Worms...they give a good fight.
