A little late, but very cool nonetheless. I'm not actually sure which of the numerous explanations I believe, but hey....
I indeed noticed the super-sized moon on Tuesday night (the 21st, before the moon was actually full) when I was doing some late night windsprints with Veloce on Memorial and Storrow Drives. It was crystal clear, fantastically warm and dry, and that big ol' moon was shinin' shinin'.
