Here is yet another cool Melloblocco related piece of news. A crew of guys in jolly olde England have a service called "The Boulder Bus"
It has standard trips from England to Fontainebleau and they even drive across the Atlantic Ocean all the way to Oregon, which I assume is correct, unless there is some crag in the UK called Portland.
OK, I guess there is a Brit crag called Portland. But I prefer my theory of driving a bus across the Atlantic, because that would defy physics, which is really cool.
Anyway, this year (as they've done for previous Melloblocco events), they are offering a shuttle service from the Milano airport to Val di Mello. I don't know if they have some kind of inclusive service all the way from England, maybe you should contact them.
And by the looks of it, this rig is NOT some jingus, piss-smelling Greyhound Bus. It's fully decked out: a few beds, DVD player, Xbox, little kitchen, etc.
