actually that would be pretty cool. In the future visitor centre (based in London for convenience) there'll be a virtual reality exhibit (with treadmill) so you'll be able to do exactly that.
Anyway, if they make you walk a mile to stonehenge and then you can't even get near the stones, well, I don't think most people you see visiting now are going to bother, and english heritage are going to lose a lot of money.
We drove past it at stupid o'clock Sunday morning and there were at least two people in there amongst the stones. I hear you can arrange it in advance and stump up some cash. I want to go. It's not the same if you can't get near the stones (not that you want millions dropping their ice-lolly sticks round it). I don't like to think of it being disneyfied, it's bad enough as it is. Or does Stonehenge have to be the sacrificial honeypot site, destined to be abused forever.
