Oh it's a conspiracy all right, but it's nothing to do with those aliens (they'll be using the Large Hadron Collider to create a worm hole between Earth and Rigel-7). It is in fact a Europe-wide Stalinist programme to restrict movement. I knew that EU Contitution / Lisbon Treaty / Whatever It's Called This Week was bad news!!!
Incidentally, I've actually been in an active (but not erupting) volcano - Nisyros. It's one of the Greek Dodecanese islands (near Kos), and it's quite odd because the crater is full of solidified mud, so you can actually go right down into the crater and stand on this mud. There are holes which vent steam continuously, and bubbling mud pools. It was very interesting, but there's a terrible eggy smell due to the sulphur.
