To tell the truth I would ask when I went with them. I have more trouble finding parking spots near where I want to fish than fishing spots. I suspect that is even more so in RI than Maine.

I think once you show someone a spot , the best you can hope for is that he doesn't show others. You should expect he may start going there on his own. A lot of spot "swapping " goes on too. You tell someone a spot and they tell you one , etc. People have always done it.

You want to be careful about spilling the beans where the word will spread rapidly. tell a tackle shop guy and the whole shop of people will be there the next day. Tell it on the internet and you'll get people from the 3 states swooping in on you.

My "spot" is 8 miles long.
