I sent them this

*****************
WOW ... am I mean WOW. Totally awesome trip you went on. I spent a few days in the area last year and was sucked into th magic of the hill. What I would have given to go inside myself. I have nothing but respect and envy for you journey to the centre of Silbury.

I would have been freaked by those lights. I suppose you may have been too if you had noticed them at the time. I was spooked just seeing them on the photos.

Totally awesome thing you've done. To find out so much about the shaft and record it for us all to share in.

Thankyou so much
