It's funny, in the regular world, I'm pretty critical of the way I look and the way others look and act.
But, when I'm backpacking, I could absolutely care less. The way I look at it, when I come across others on the trail or in camp, I'm walking into there living room. The same way, if they run into me, they gotta deal with it as if they are an intruder in my house.
If someone finds it easier to step out of there tent in there skivvies to get dressed, don't bother me, and I do the same. Wanna go skinny dipping or underwear swimming, that's your perogetive. I've been know to strip down to take a bath and rinse my clothes off in a creek. I'm not gonna do it 5 feet from you, but if you walk up on me, I won't be diving for cover like I might in the regular world.
I wear what's comfortable or practical, and I assume the same of others. Wanna wear a lime green shirt and florescent orange shoes, be my guest. Don't be surprised to find me walking around with a dorky looking brimmed hat with a bandana hanging out the back to cover my neck. If it's faster to stuff a wind shirt or rain jacket under some cord, then it's gonna hang out of my pack all janky, rather than take the time to stop, take my pack off and find a place for it inside.
I don't look at the boy scout wearing a 60lb pack with pots and pans hanging off of it, any different than I look at someone with a 15lb pack that's all nice and tidy.
Hike your own hike is the way I look at it. As long as you are outside, having fun and not getting hurt or endangering others. Oh, and if I catch you littering, I don't care if you look like Brad Pitt, I will beat you with my hiking sticks and feed you to the bears.
