expeditions

Matt Tidy - a guy I work with says (he did it as a comment but my fingers are big and my iphone is small so I hit delete instead of publish...) -

Best of luck with the group!
I work with Alan but I used to organise expeditions, let me know if I can help out sometime..or if any of you are keen for a river expedition somewhere adventurous I can help with that too!

He does this sort of stuff...
