I had no idea that Jay was THAT casual about his secret identity early on. Thanks for reprinting these. I notice they also kept the speed to more realistic limits---a thousand MPH, not faster than light, in these early stories. Today, Jay (or Wally or Barry) would cover two thousand miles in two seconds, not three hours.
This reminds me of the Human Torch's early run in STRANGE TALES (the Johnny Storm one, not his android predecessor) where even though everyone knew his sister was the Invisible Girl, supposedly nobody except a few friends who had left knew Johnny Storm was the Human Torch, and he pulled various tricks to have room to change his identity.
This went on for a little while, and then the high schoolers he was "fooling" revealed the truth---they had known all along he was the Torch, and were just giving him his space, as it were, if he wanted to pretend to be a "normal" teen-ager.
