Bobo raises a VERY valid point. It is easy for us computer-savvy people in our prime (or thereabouts) to get all righteous and say "ignorance is no excuse", but just stop and think for a moment...you are a 70-80 year old pensioner who chose not to get (or couldn't get) into the computer age, your old lady gives you some crap after church on Sunday, and you decide to hit the river with a bar rig and some roe to get away from everything for a few hours.
What are your options as to being up-to-date with in-season changes, especially those overnight ones they hit us with sometimes?
Nothing is available on Sunday, there are few tackle shops left, the public library is closed, there's no signs on the river where you fish...if I were a CO, I'd probably give an elder gent a break the first time - give him a warning and confiscate his bait. When you are on fixed income, even a parking ticket can set you back big time, let alone a fishing regulation violation ticket. Remember that not all offenders are created equal and a little bit of sympathy goes a long way. Especially for the elderly among us.
