Back home a while back a guy would leave old beater cars on the ice to go through when it thawed in spring. Pretty good spot for gators now.
I once took a 1 gallon glass jar, attached a rope to the lid, and filled it with water, a dozen live minnows and a glow stick and then lowered it to the bottom and jigged next to it. I never got a bite. Does'nt this sound like it should work? I was sure it would, but it didn't.
