I remember seeing Harry toting two Nikon F's around his neck...one had a 300mm f/4.5 Nikkor and the other had the monster 85-250 Nikkor. One body had the F-36 Motor Drive and the other body had the F-250 Motor Drive attached!
He looked awesome, wearing tie-dyes and a cowboy hat. It was early June 1966 or 1967 in Central Park at an Anti-Viet-Nam War demonstration. I was covering it for my college newspaper and was shooting old Ilford HP-S with an 18mm Rokkor on a Minolta SR7. I still have the negs...beautiful memories!
