This Saturday, hop on one of the 27 trolleys that take residents on the convivial, 45-minute Illuminations Tour of Somerville's Christmas lights. The first will leave City Hall Concourse at 4:30 p.m and return there after the tour ends.
Back at City Hall, there will be coffee, hot chocolate and cookies, as well as choral music and crafts for children.
Trolley Tour tickets will be available at the Blue Cloud Gallery, 713 Broadway, beginning Wednesday, Dec 1.
Tickets are $10 for adults and $5 for children and seniors.
If you'd rather see Somerville's Christmas lights by bike, join the Somerville Bicycle Committee and other cyclists this Saturday.

There is a $5 suggested donation to the Somerville Arts Council.
