I was just reading this and wondering if we are going to see sky rocketing prices for fuel due to refineries and terminals being shut down. From reading past posts I know there are a few forum members who know the ins and outs of the business, hopefully they can chime in.
If you haven't already found people that you would want to communicate with in a crisis, and formed some kind of at least informal network of those folks before you need to use this technology for SHTF communications, it won't help.
