Happens every year. I just meet a whole gaggle of NOBO stragglers at the Gorham, NH Walmart this afteroon. Close to a dozen I'd guess. With only about 3 weeks left to do almost 300 really tough miles, they better hope for some really good weather the next couple of weeks or that Baxter stays open late this year. At this point it's a little hard to say if they will get that extra week or not.
Usually the ones who get here this late in the season are the ones who have been taking it easy and/or partying the whole way. For them to suddenly find religion and do serious miles through Maine at this point is questionable, but I wish them luck!
