I'm constantly surprised by what other people don't like. The brightly colored camping gear never bothered me, neither mine nor others. It brings to mind an online rant I read about wagon tracks someone found worn into the bedrock in the mountains near LA (sorry, can't remember where I read it - it was years ago). The writer was clearly angry about the scar humans had left on the landscape, but to me it just adds to the charming history. The notion of a completely untouched pristine wilderness is fantasy.

EDIT: Having said that, I don't like noise pollution like when people listen to music out loud on their phones in public.
