I've done a lot of what Oldsarge said above.
There really isn't a choice in survival school nearby to me, I'd have to travel several hours to go to one. As with just about anything in my area, there just isn't anything local.
So, I went to the library and checked out some books, bought some off amazon, and have self taught myself several things. I have put together my own survival kits, and practiced with the items in them. I get them out every now and then and try to keep up with the skills, and only use items that are fairly easy to work with. You never know when you may be injured or panicked, and not be entirely capable to use items like you would on any regular day.
I've also self taught on basic navigation with map and compass, and some more advanced ideas as well. I also go out every so often to practice locating myself using resections, modified resections, dead reckoning, GPS, etc. I also will plan routes, obtain coordinates from the map, and attempt to deal with declination. In general, I use a compass with adjustable declination, but never know when I'll get stuck using one without it.
Still, I would love to be able to take some classes in these fields. I'm sure I could learn something new, plus it would validate whether or not I'm doing things right or just close to right. They can't be completely wrong, or I would notice that (hopefully).
I've also thought, if I could take a class and see how they are taught, I could at least come back home and teach the basics in my area. Things like GPS, Map reading, Compass, and basic survival ideas. Right now, I don't really have any idea on how to teach a class in those areas. I could probably wing it if I tried. I'd just like to know I was doing it right first.
