I'm a massage therapist in central Florida. I have literally had my finger on the pulses of rednecks and others. Unfortunately I have met many people pissed of and/or frightened because we have a Black president. I've heard a Black man can't be intelligent enough for the job, I've heard the birther stuff, I've heard that he is a secret plant of the Islamist Jihad who before he became president was able to engineer the recession so that "real" Americans would lose everything and Blacks would take over. And I've heard some people say the sort of things that can bring the secret service over for a chat just to make sure you're not serious.
Not all racism is blatant. Some of the most shocking to me has come from people I never would have expected it from, and they have mostly been older people who grew up in the south and would not otherwise hurt a fly, who'd give a hungry Black person the shirt off their back, but who are unable to get over the Jim Crow culture they grew up in in which Black people just aren't quite as good as whites and need to stay in their place.
We've come a long way because of brave Americans who have stood up for the values of our country. Things are certainly better then when I was a kid traveling in the south and wondering why some water fountains had "whites only" signs on them. But a couple of years ago a neighbor put on a haunted house and he was telling a little Black kid all about it and how all the kids were invited and this little guy said, "Even little Black boys?"
OP, many people will tell you the chances of just seeing a bear on the AT are slim, not to mention getting bothered by one, and you can just about forget about one hurting you.
But I keep my eyes open.
