You can say that again. We summered up in Maine when I was growing up and that water would turn you blue in two seconds flat. When I was a kid I could swim in it but now? not on your life!
Skunky, I haven't personally kayaked up in Maine but my sister lives there (in Bangor, just south of Mt. Desert Island) and she would tell you that though the coast is indeed beautiful and enticing to explore by kayak, you ought not to do it without someone experienced because of the very challenges that the article pointed out. The Maine coast does not mess around.
