Arf!
Well, I'm pretty sure Gordon's gone on to have some pretty successful experiments with stone transportation. It was a shame the televised one didn't go to plan, but we were rather governed by when the cameras would be rolling. That, combined with the fact that the method was still pretty much in its' infancy, I feel, contributed to the fact that we didn't do as well as we'd hoped to do, as far as stone-rowing went, at any rate.
As you so rightly say, though - pulling it with ropes and rollers surprised the hell out of all of us with how easy it was! Especially poor Simon ;) (whatever happened to him, I wonder - nice bloke!)
So dragging the bluestomer all that distance - while being time-consuming - would have been easy enough I reckon. And if the stones HAD been deposited nearby by glacier, them even easier still! Although the quarries in Preselli are intriguing. The half-quarried bluestones don't half look familiar! ;)
