When we plan a trip I try to anticipate 'am I gonna do some fishin there' then I research licensing. Over the past few years, states have jumped on salt water licensing big time. Most states the cost is reasonable. The fishing laws can be confusing.
I came close in FL---Some fish you can not lift out of the water, they must be released in the water. You better have a good release mechanism. and the right style of hook.
In North Carolina last year, I was stopped twice for a license check, surf fishing on the beach and coming ashore in my kayak (Pamlico Sound).
I like PA's law where you must show your license, i.e, wearing it on a vest or your hat in a plastic holder.
I always feel the MAN has his binoculars on me, especially in FL, and that's OK. I just wish states do like PA---Show the license---not just have it on your person.
