[Richie goes to one of the safe zones because it's easier than trying to fight when he doesn't have any of his gear or weapons to use. Rocket skates are not enough to handle what could be out there. It makes him feel a bit like a coward, but he also knows that sometimes you have to accept that it's better to play it safe than to get in the middle.]
At least there's a few sci-fi to pick from. So...Raiders from Mars, or Assault on Space Station Alpha, or It Came from Beneath?
