I'm going to be in Nashua next month and will be on a pretty tight budget. I'm looking for the best free and inexpensive things to check out! I love the outdoors, art, museums, you name it. Thanks!

Walk Main Street in downtown Nashua to get a sense of the town. Stop at city hall to see the spot where President Kennedy announced his run for the office. You'll find three cafes downtown, inexpensive places to hang out and read or surf the Internet:
