There's a ride every Tuesday at 10 in Harvard Sq.

If you want an adventure, bring a camera and see how many of the painted cows you can get on film.

Places to go: P.O. Square [personal favorite], Museum of Science, Aquarium, Public Garden, Isabella Stuart Gardener Museum [unique, required viewing], MFA, ICA, Boston Pops concert [PM me and I can sneek you in].

Bike shops: I partial to Cambridge Bike.

Restaurants: The Daily Catch, the No Name, Red Bones, Grasshopper, and all-you-can-eat desert buffet at Four Seasons on Fridays.

edit: Did I mention you have to go to the Gardener Museum?
