Having spent most of my college summers and winter breaks temping in downtown Boston, I really feel for Downtown Crossing's recent struggles, as various anchor retailers have left the area. This weekend, consider heading downtown to enjoy the holiday events that are part tradition/part revitalization effort. From 11am – 5pm you can take advantage of shopping deals, take a photo with Santa, enjoy refreshments, and visit the holiday petting zoo. And for little train enthusiasts, South Station’s holiday train exhibit is just one T stop (or brief walk) away, down Summer Street.
