Tickets go on sale today for the Somerville Illuminations Tour. Annually I have wished to join the merry crowds on their trolley tour of Somerville’s most sparkly houses, but something has always come up. This year, I will not be deterred. Mark your calendars: December 18th; $10 a person. If you can’t make it, you can always buy the charmingly chintzy postcards inscribed with “Greetings from Somerville,” or the self-guided tour Map from participating stores.
