Playing in the hallways of high school between classes and during lunch breaks for nickels and quarters.
That was over 50 years ago. There were many years in the middle where the games thinned out or disappeared, but about 6 years ago my life evolved to allow me to get back into the game.
The main difference between then and now is the dominance of NLHE, which didn't really exist back then. In many ways, I prefer the mixed games/dealers choice of the past. The poker boom seems to have killed that, in that most players who began in the last 20 years or so only seem to know (and want to play) NLHE. That's a shame IMO
