Maybe it's possible that this little town where Megan sold the machine is off the map and b/c we are so busy (???) we didn't even consider looking for it...so, when Marco Polo McKee ventured to the other side of the world he just assumed the town would be in an ordinary place...not sure that's the way it happened...I guess we'll leave it to the intrepids to sort it out...just want to make one comment: God is in the details................
