Actually Annabelle there is no such thing as J Vegas. I consulted the oracle that is the tussock monster this morning and in his infinite words of wisdom he said it is J'Ville. The acronym that is Vegas has to be tagged onto a tourist town ie Roto Vegas, Franz Vegas, Puna Vegas etc. Since I am in Franz Vegas for a couple more weeks I have to concur with he who knows best. Therefore your dictionary or atlas has got it wrong (yet again), and has to be disregarded and re written. You have to give some sort of sacrifice to the tussock monster for this abomnimation.
