The chain link fence did it for me spent many-a-day riding the Ossa trials bike around it looking for a hole to escape from!! could quite muster up the nerve to do a Steve Mcqueen, ala the great escape!! I seem to remember they all had Spinlebury Tindal HF's then with the whip arial and YX being the first one on-site with the (cant remember the name) wire down the tailboom, I remember doing the ferry across the Sahara with Bob Roffe.
