Thanks for the replies. I am going to have limited time so pretty much any spots on the Kennebunk near the hotel is what I'll be hitting. I'll probably give it a shot though.
It's an estuary/river bite that early. I catch fish up there as early as first week of May no matter how the weather has been. Mousam R is easy, Saco R may have more fish then. Lack of runoff, mild winter maybe fish will turn on in April.
