Thats an interesting question. The answer of course is long, complicated, and convoluted. Long story short, they left the house because (now, wait for it, this is good) the Television
told them to! I know, I know, bear with me; in an attempt to better their ratings, the TV news programs amped up their coverage of the impending wild-flower season. Why? you ask. Again, its complicated. Why would the TV stations try to lead people away from their quality info-tainment? It's actually about to come full circle... If the unwary couch dweller wanders outside his (or her) natural habitat they are bound to become severely mis-located (that is to say, "lost"). This ensures the Networks' ability to bring sensational coverage of "dramatic rescues" of "hikers" in "rural areas". Hence bringing more people back to the (gasp) Television
I know; your impressed.
(see what you get for asking a rhetorical question?
Wait... Which Matt were you asking?
