The weekend before last we went to the Boston Local Food Festival on the Greenway in Boston. While we used the opportunity as our one fancy “nom out” for the month (see this post for details on our monthly adventures), there were loads of free samples, a cooking competition, and demonstrations all for free. We even got free parking using Spot Hero**).
There are so many great, free activities in any city, and this post is a guide to what’s available in our own neck of the woods. However, most of the tips are valid across the country. This doesn’t cover the most touristy things you can do for free in Boston (freedom trail, etc), but Boston on Budget has a great article covering that base for your reference.
