You might enjoy this website; it's called "Jacktrack," and it shows on a map where Jack's gone in a given episode (along with snarky comments about how likely he actually would be to cover so much ground in LA traffic in so little time!): http://www.wayfaring.com/maps/show/4698

But I agree wholeheartedly about Chloe. She must die. :-)
