I don't draw from that fiasco an inference that they'd be happy to stand by and watch a few thousand revellers topple their biggest money spinner.
What!?
In what way are the 'few thousand revelers' a 'money spinner'? The few thousand revelers get in free! In fact, if anything, the 'few thousand revelers' are costing EH money not make them any!!!
Calm down, LS! Read what I wrote. I was referring to Stonehenge as their biggest money spinner - not the solstice crowd.
