Yes, and you can do so by buying a big, gas guzzling SUV, truck or RV.

This all happened after a report said to prepare for lower oil prices for the presumable future.

I am not normally a conspiracy theorist, but Russia has asked why the US radar missile detection system did not notice these drones. That leads to the thought that if they were launched by the Yemen Rebels, they would have had to travel some distance and about the only way to evade is very close to ground. If that is true, the blueprint for future attacks has been revealed. In other words, this was both an attack, and a test run for the future. If the attack was from Iran, then that is even more of an indictment of the radar detection systems as it would be presumed that Saudi Arabia is already worried about Iran and has radar aimed there. OR, it was staged by SA itself to provoke Trump to send troops for perhaps a ratcheting up for future actions.
