Yea Smooth, I enjoyed meeting you and Waldo near Zealand Falls hut (i think) and most of the SOBO's were friendly. I don't think you can categorize any one group. Every group will have a few bad apples and many good ones. In fact, what you say about NOBO's was somewhat true for SOBO's too. The first couple I met rubbed me the wrong way, as they had little regard or interest in what I said and could care less about any information or advice, though that could be the product of having many NOBO's in front of them try to interject their thoughts on them continually.
I always thought it was funny that the closer I got to Katahdin, the more questions the SOBO's asked, the more inexperienced and the shorter the beards
