I just remembered an incident that happened to me on the Delaware that I'd forgotten. About ten years ago a buddy and I put my two man kayak in at the Buckingham access on the Delaware River. We planned to just do a short float to the Lordville Bridge a couple of miles down river. Well we had floated all the way down until we were about 100 yards above the bridge. I should mention straight away that we didn't have any PFD's in the craft and I didn't have my fishing license with me.
I saw what looked like two NYS fish wardens right at the bridge checking everyone in, and out, of the river. I told me partner who I thought they were and said "let's stay here on the PA side of the river until they leave". Haha, that was funny because they turned out to be Federal wardens and they just got in their vehicle and drove across the bridge into PA. Both got out of their vehicle and walked down a very steep hill and motioned us over to the shore.
I remember one of them saying, with all seriousness, "Who is the captain of this vessel?" I'm not kidding that is what he said. I said I was and he asked to see my fishing license and I told him I didn't have it. Then he asked me my name and wanted to see my driver's license so he could verify my statement. I told him I had left my wallet, with both my driver's and fishing license, back in my cabin.
Luckily for me he had a hand held computer and was able to verify the name and address I had given to him as well as I had a valid NY and PA fishing license. He gave me two citations, one for not having any PFD's on board and one for not having a "sound producing device" on board. I think the fine was $50 back then and my buddy graciously paid for half the fine. The wardens also told us we had to exit the river immediately and the next time I saw them I better have my drivers license and fishing license with me.
