This is a strange topic. But I notice that at the spring nationals for the top swimmers in the US not master types that only 2 teams have survive that were around in the 1960's. Santa Clara and Arden Hills. Arden Hills was famous for Mark Spitz and Debbie Meyer. Now Arden Hills has only one swimmer that made nationals. The other teams back in the old days are all college teams. Also, notice Phelps who team was founded in the early 1970's is as hot as always with a 200 meter back just .15 from the world record.
