One of my earliest memories is catching fireflies in the backyard while my dad and his friends listened to a baseball game on the radio. It was dark and all you could see was the glow from their cigarettes. I must have been about 4 yrs old. The jar for the fireflies was glass with holes poked in the lid so they could "breathe". Nowadays, dad would be in trouble for smoking and letting a little kid have a glass jar.
