  8. Bill and I met approx 1944 . We lived in Bellcrest East Northport. We enjoyed our youth swimming fishing scuba diving ( without that new fancy gear of today ) fins and mask and wooden spear.we would swim from Crab meadow beach to ashroken coast guard area . We had so much fun driving our old cars ,Bill drove an old chev cabriolet a beautiful car and he would ride his motor bike on his dads property . We lost touch with each other for years . Times were difficult then Ww2 was ended ,Korea was starting. The last time I saw bill was about 15 years ago .we met in smithtown and had lunch. I’m sorry I’m late in seeing him again , but time runs out and we are all left with memories . Rest my friend ..you old diving buddy .Mike Affatato
