For those interested, I thought I'd post this map which gives fairly detailed locations of the locales mentioned and seen in the episode. It will be a good guide for making the articles. --Noah Tall (talk) 13:25, June 1, 2015 (UTC)
Interesting. After examining this map and watching the episode it seems that Grover's Corner (the dot that Batman points to on the map) is the white dwarf crash site. I'm not sure I understand how that's possible considering the pickup trucks were supposedly "snatched up and carried away," implying they were gone, but when they go to that location on the map, there they are.
