AS you joined literally earlier none of us have a clue who you are mate,maybe bung some threads up of what you have done and maybe help would be more forth coming
I've not done alot to be honest, few abounded buildings here and there but I only live 40 mins from box and I've got the kit to help me get around it.
One way or another I'll find a way in (without breaking anything I should point out) I had the opportunity to go last year but didn't and regretting it now.
I've found some maps online and various old entry points so if need be I can go by them but would rather something that has some reliability rather then internet finds.
Sorry I dont mean to sound rude but I know what you mean I could be anyone.
If anyone fancy a trip tho of a weekend I'd be happy to join
