What do you consider "fringe"? By definition, at the present time the entire topic of PX is considered fringe, so anyone who is taking it seriously is also considered fringe. The most complete info on PX and how to survive it is probably at www.zetatalk.com, but they are also probably the single most maligned website/group at GLP.

My general advice is:

(1) Stock enough food and basic gear for the first several months, a period during which things will be in total chaos. The whole package shouldn't cost more than the price of the average person's car insurance bill for a year.

(2) Keep working on those wilderness living skills, particularly in relation to food: learn all the edible plants in your area, learn how to hunt and trap (trapping is more efficient than hunting because you don't have to be there to do it; also, deer will get hunted out quickly after a pole shift, but small game like rabbits will not).

(3) Find areas away from population centers with water and some measure of isolation. This could be one's own rural land or it might be on, for example, national forest land. Get maps and spend time in these areas in advance scoping them out for access, water, hunting/gathering prospects, etc.
