I'll tell you a little story, WD Skelton, IMO the best barrier jock I rode against, one day he drew next to me in 2, a field of about 24, he's got a bumper [cig] in his mouth, we spoke about nothing important if I remember but a little natter, as the last one came in he stubbed the cig out, wiped his mouth and the stater called out, ''all clear''....and we were off.......all clear.......Bill was very laid back, as was Bob.......but calling out all clear meant action time boys.....no gals back then.......somethings changed, as it does......I have no idea......literally.......Pam might ask her ex, he would know more I suspect.
