With the mild winter, I'd say Sully's got his finger right on the jugular. This probably means an early smallmouth spawn in the north lakes and among other things - a bad tick season. Roll them socks over the pant cuffs if you're bushwacking without waders - Lyme's disease is a 'bug' in the same spirochete family as syphillus. Seemed the herring showed early as well, and the blue heron rookery on rte 2 in Thoreau's Concord MA was here at about the same time.
An old timer once told me that by the time the apple trees bloom the stripers are thick on the coast. Of course they are here before that but for any consistency the blossom rule is a good one. It also helps frame your intentions with your significant other - "look dear the trees are in bloom!".
