I've been fishing all my lines blind for 5 or 6 years. I'll get an occasonial line set out across mine. I run my lines everyday, and can tell if the line across mine is a weekend line or is being baited often. Weekend trotline...you got 8 days to bait it or take it up or it's mine.

I've ran one of my lines for a month with another guys line across mine and he was baiting his line every other day with slicks and we were both catching fish. He picked his up one day. Never seen him.
