Argh.
Just for a counterpoint: I do not hike to meet people. I do not like saying "Hi!" dozen's of times. I have no interest in striking up a conversation with anybody. I will, however, be polite respond to greetings. I also help others when needed, answer pertinent questions, etc., etc..
I like to hike solo - just me and the mountain - regardless of how many other people are on the trail...
I do not pass judgement on others, and I prefer to not be judged (but this is 'Merica, so WhatChaGonnaDo?).
So there. Take that, all you friendly meet and greet people. Shoo.
Other sins of mine include using a GPS on every hike (gasp!) and listening to music via ear buds (oh yes, I go there). Oh, and hiking solo at night. I think that makes me the most evil hiker on the trail ever (imagine evil laugh here).
Can't a guy just go for a nice, quiet hike?
