I'm an Aussie living in Florida these days, and I'm in the early stages of planning to do the entire trail next year on my own.
I've been doing a bit of homework on various aspects to the hike, but one that has me a tad concerned are a few points I've read here and there about one or two sections of the trail that come across as fairly hazardous in the descriptions I've read. Don't get me wrong, I've tackled stuff on my own hiking back in Australia that I look back on and wonder where my sanity was to attempt them, but I'm also in my mid 50's now and just want to nail down exactly what I might be dealing with so I can anticipate any problems.
As for bear encounters, do any trail hikers, especially those going solo, bother to take bear spray along? We have bears roaming our neighborhood constantly, and I've come across them in Yosemite, but I've never come across them in the wild, and even though I've read up on all the literature about what to do when encountering one I certainly have no knowledge of what the average trail hiker does or doesn't do in terms of securing themselves against potentially aggressive behaviour while hiking alone. I'm guessing most people just wing it and count on natural fear of humans to get through any occasional encounters? I thought about taking along some kind of little bell or other noise maker to help alert any animals to my presence, but figured that it would drive me crazy hearing the damn thing hour after hour, day after day!
It's kind of funny actually, all I ever get from people here are about the potential dangers from hiking in a place like Australia with all of it's venomous snakes, yet aside from basic common sense and knowing what to do if bitten no one really gives them a thought and just gets on with it, other than developing a radar for looking to the left and right of the path as you walk along to keep an eye out for them. On the other hand we don't have large carnivores to worry about when out and about hiking, or woods full of crazy hunters looking to shoot anything that moves during hunting season!
