Damn old, but I can most likely outrun and even outlift ya !! Not a bragger though, Wiggs. We did meet and talk at one of the Oly expos a couple of years ago if you are the same Wiggs from LV.
If I recall right ... Bob Gadja from some well known hard core gym in Chicago was Sergio's biggest challenge in one of the Mr America events he entered but a good looking kid by the name of jerry Daniels upset the apple-cart that year. Long story to that one.
Maybe one of your official historians can elaborate. I was there but I'd hate to give inaccurate information due to the vast number of years that have passed since then.
Those were great bodybuilding days back then. Nothing like today!!
If you don't believe me, ask Gene Mozee.
