You may or may not know of the unprecedented Solar Eclipse on August 21, 2017. The last time an eclipse of this size and totalitary was about 100 years ago!
BP Earth does a terrific breakdown of the event for you and gives you a "heads-up" on the Department of Transport posting warnings of the amount of traffic problems as well as heat-wave problems for people across the States who may get caught in traffic due to everyone wanting to have free tickets to see this one in a lifetime eclipse.
Great advise.

Very cool but I don't think it will cause traffic at all! Most people will be at work during the eclipse.
Fair enough! Let's hope all enjoy it, even me here in Japan.
