Somerville Open Studios is an event not to be missed. 401 artists in twelve hours? That gives you 1 minute, 47 seconds to see each artist. Good luck! No one hu-man can possibly see it all without the aid of time travel devices. If you don’t have one handy, check out the Somerville Museum: they’ve got the artist’s choice exhibit, which acts as a targeting computer for your brand of talent. Romer is there, posting watch.
