Okay, it's a mountain at 1820 feet. But you can drive to it at the 1700 feet level. That makes it a climb of only 120 feet and probably, by far, the easiest firetower climb in the "challenge." That's okay. There is a firetower and a great view at the top, all the way to Lake Champlain and Vermont.
But the kinda weird thing is that we did Goodnow Mountain on July 4th. While on top a couple and a young boy arrived while we were there. Three days later, in the afternoon, we met the same couple coming DOWN from Belfry, just as we were headed UP! We had a nice chat about, "What are the chances" of such a meetup? Guess we're all having fun and on the same schedule!
