In case readers are looking for something cheap to do during April vacation week…
The National Park Service is celebrating National Park Week from April 16-24 this year.
That means you can go to any National Park for free during that time!
You can find a list of parks (like Boott Mill, pictured left) in Massachusetts on their website.
