"how tough is is to get your pontoon or in my case my watermaster out by the mouth??"
With the tide change in the afternoon you could row a pram out there. The morning has the low tide and in the afternoon the water comes in and really slackens off. By 4 o'clock pm or so it's at it's slowest current and highest tide tommorrow. I see people in inflatables out there so just time yourself to the tides for easy rowing. As for catching fish down the lower end, there are the obvious spots that you can catch the ones holding up. They jump all the time showing themselves and if you keep at it they bite on a variety of lures I'm not sure which fly would be the best for them. I like trolling for the fresh ones as they provide the best action as in fish per hour. If there isn't a new school around, I do not hang around too long. One of my favorite places to row around and fish anyway, fish or no fish. Beats bank magotting.
