I was 9 years old and standing at Hilberry (back then it was spelled with just one L) in 1967 and watched Mike come past lap after lap. This is no word of a lie, but as he left Hilberry flat-chat, his rear wheel was continuously skipping left and right on the straight, always at least a foot, but sometimes it would skip two to almost three feet left and right. The crowd gasped in awe as Mike wrestled the bike back on line. As you can see, I recall making a mental note to remember what was happening, as it seemed unbelievable.
