As pete says ...GO FOR IT ! .
I contacted 5 people off there and (i was going to keep this quiet till the trainee form was signed but feck it ) i managed to get a taster day with a chap only half hrs drive from me, all things went well and he seemed to be impressed with my early arrival more than anything really , i did ring 3 birds which was nerve wrecking but hey ..ya gotta start somewhere. i was in the company of my "future" trainer and two other chaps who blew me away with all the "bird" talk between them....it was a feckin great morning out and i cant wait for him to call me for
