My oh my, what fun it would be to tap into THAT keyboard and make your own highway signs. The humor advantages would be endless. Then again, getting thrown into the hoosgow in NJ would be less than fun. So maybe I shall refrain. Like I could hack anything anyway. Closest I get to that is local kitty hairballs...
Haha, yeah, it's only a matter of time before one of those messages drops the F-bomb ;-)
