I was not the only crazy person walking around Castle Island today, although I was the only one not in a jacket (but at least I had the sense not to venture onto the fishing pier, onto which the occasional wave crashed). I watched boats jumping into waves and a fair number of seagulls and terns divebombing the choppy water (fish down there?). The planes heading to Logan swayed as the pilots fought the wind - and as their wings trailed streamers of mist.
