Jumpin Jack sign on Highway 495 Southbound

There's a modest sign on the roadside of Highway 495 South, about halfway between Highways 2 and 111. It is simple, with an American flag, and the words "Jumpin Jack". I've wondered what Jumpin Jack was.

Well, he turns out to be a beloved local truck driver named Jack Albert McPhail, a local hero that died while saving others on fateful winter day in March 2007. The story was originally carried by the Boston Herald, but is no longer available.   I was able to track down a Boston Globe article on Boston.com.  It does not mention the nick name "Jumpin Jack".  An obituary still appears on this trucker's forum. It's a good read about the man who was apparently well liked in his community.

For anyone that can safely use Facebook on the road (i.e., a passenger of a car) while passing this sign on 495 S, I've added a place to Facebook to check-in at this location called Jumpin Jack Memorial, classified as a local business under Highway. Facebook is a little odd on how it handles places added by common users, so you may have to search a bit for it (which is why you should be a passenger to attempt the check-in).
