Gives the bread and butter $$, but found some small family owned oil well pkgs.

Would love to hear about your journeys to $1M net worth in real-estate and oil & as investing.

However, he's a snake oil salesman. 

I walked away from that deal because the inspection found a leaking underground oil tank.  

Strangely however no one is talking about the systematic devastation and migration that could emerge in cities and small towns with single economies like Casinos, Theme Parks, Tourism Resorts, Oil belt and College Towns.

Thanks James, I'm surprised you don't have to wash your hair or shave your legs right about that time LOL!!!

@Jacques Ridore it appears I'm late to the party and your question(s) have already been answered.

I have had great success with an essential oil defuser and an essential oil mixture called Purification.  

As mentioned by the other people here, lots of snake oil being sold out there now days!

However, where creating a moat might not be feasible, creating a steep hill(with a few archers and a dude or two pouring boiling oil down on any would-be encroachers) might be possible.
