This is the greatest bummer sticker. It is a bummer because it reminds all that if you attempt to enter the Area 51 Groom Lake Research Facility you could be met with deadly force for the use thereof is authorized. Real bummer. But feel free to put it on your bumper so that the person behind you will know what you already know…”Research facility” right. Why would a research facility allow the use of deadly force unless they were researching something they very much like to keep quiet? Get one today.
