The weather was so nice again that I decided to get outside after work, rather than wait for the weekend. I decided to drive east on US-4 to look for the Northern Rail Trail again and try to hike another section. I was able to find a place to park in Grafton Center headed towards Boston. Walked just under two miles (one way) to the Grafton Post Office and back (between 1800 and 1900). The weather was perfect for an evening stroll - there weren't a lot of landmarks in the section but, as always, the mountains looked pretty in the twilight...
