Ok. Pay attention (ignore the crappy music, but tune back in around the 2 minute 20 second mark):
Talking water. Cool. That was clue number one for Vanishing Point in Las Vegas. Normally Nevada is a little further outside the M25 than we prefer, but in this case we'll make an exception as a similar clue is due to arrive on Saturday the 20th in Trafalgar Square (50'30' 29.21"N, 0'7' 41.27"W) at 7pm.
If you want to know what we're talking about check out BoingBoing.
Not sure if our clue will be another talking fountain, but we'll be nipping along to film it. See you there.
Thanks to Michael Reeve for the tip and congrats in getting tickets for the Hot Fuzz preview - sold out VERY quickly we hear.
