This man was a world famous poet who lived here and taught at Pinkerton Academy. One of his well known poems is "Stopping by the Woods on a Snowy Evening."Well, duh! Not much here to entice you to visit! On the corresponding map, the #2 is barely visible! Not much "walking" is involved, either. "Walk into History" was a good idea, poorly executed.
If you want to visit Frost's Home (also known as Robert Frost's Farm), go the historic site's webpage. Here you'll find information about the farm, events, poetry, and a trail you can WALK on!
For more historic walks close to home there's the Lowell National Historic Park. A little further afield is Boston, which John Harris has written about in The Boston Globe Historic Walks in Boston [917.44 HAR].
1,000 Places to See in the USA and Canada before You Die by Patricia Schultz [917.304 SCH] will lead you to many wonderful places to visit and walk!
