While it is certainly "interesting" and quite sensationalistic, you may wish to studiously avoid mentioning in your speech that many of the supermarket tabloid newspapers and many conspiracy-theory websites claim -- with some justification -- that the sport of geocaching is heavily subisdized by the space aliens (the malevolent alien grays, that is), and that the entire sport of geocaching exists largely at the behest of these space aliens, who have their own evil reasons for luring people off the beaten track into secluded rural areas where they can abduct these geocachers, emplace brain implants, erase their memory of the incident and then release the "geocacher" back into the world as a hapless robotic slave of the space aliens to serve their agenda on earth. Yes, it is quite interesting, and also quite tragic, but it is just too sensationalistic for you to mention in your speech. You do not want half of your audience to commit suicide and the other half to go out hunting geocachers with a vengeance. Besides, the aliens might be offended if you mention their plot in public. In fact, the only reason that I can get away with writing posts such as this with impunity is that I wear my aluminum foil hat 24 hours per day, and also carry blessed holy water with me at all times in a pendant worn around my neck.
BTw, these aliens are particularly on the lookout for geocachers with gasket fabrication skills, as apparently, the aliens have a big problem with leaky neutron-flux gaskets in the powerplants on their motherships which are in geostationary orbit. So, you may wish to warn anyone with such skills to lay low and stay out of the forests and rural areas!
Maybe I should pick another topic!!!!! hahaha!
