I was at a comp in 88 or 89 at Derby or somewhere like that and Greg was riding a Haro sport which had basically no cross brace between the platform and the seat tube which normaly would have rendered it FK'd as the whole seat tube was ratling about loose. Greg just ignored this and proceeded to Rip huge airs and tweak simillar turn downs to the one in the picture. Truly one of my favourite vert riders ever.
