In my 59 years I've served 4 years in the USCG, been a barber (not hairstylist. don't go there), auto mechanic, managed gas stations, worked in foundry, sold new cars, worked production in steel fabrication plant, ran a small security company, drove taxi, sold insurance (tried anyway), framed new houses, wired new houses, plumbed new houses, did remodels and room additions, mobile home warranty work, and over the road 18 wheel truck driver. All the while pursuing survival knowledge. I sincerely hope that all of this has given me something to share here. I'm still trying to decide what I want to be when I grow up. I love to learn and I'm looking forward to plenty of opportunity for that here. From what I've been reading here, it looks like I came to the right place.
Welcome. There's some great information around here. If the SHTF, you will definately have some marketable skills.
