Is anyone up in the Dales over Easter who might then be able to deliver a small packet to Castleton (at the TSG - or to the kiosk in Peak cavern entrance)? If you can help please could you send me a PM? Thanks.

Just so folks know; thanks to the kindness of another forum member, it looks like this is now sorted. Thanks also to the other forum member (you know who you are!) who made a helpful suggestion concerning the BBs.
