They did indeed.
I had the honor of being trained by Steve when I joined the Bert Goodrich Gym in 1954. He, Larry Scott and Bill Smith were my early heros. Once they invited me to the all you can eat prime rib buffet at Rand's Roundup in Hollywood. Dbol was just making it into the gym. It was a hot topic that night including how much beef one can eat. By 1956 they had moved over to Gironda's gym. 'If' they did not dabble with Dbol they were amongst the few. For me anyway I can not say, or even care, if these men used the very legal drug Dbol. All three were great men and assets to Bodybuilding.
You are a fortunate man, indeed sir. To have known and trained with those guys is a most enviable remembrance. I have met one of my inspirations, Dave Draper. What a gentleman he is. Would that I could have met Reeves and Clarence Ross along with several more including the other two gentlemen you mention above.
Older folks such as myself have always remarked on the good old days of their youth and how it was much better be it music, movies, bodybuilding or the like. People say that we seasoned citizens are forever speaking about how life was better "back then". How music was better, movies, fashion, etc. were are better and how this has been and always will be the natural order of things as each succeeding generation passes the torch of youth.
Given the current state of what passes for music and bodybuilding I can state that we are definitely right this time. Both suck butt today and what was then is sooooo much better than what is now.
