I remember so many growing up on the so.east side, Denver Harbor to be exact. There is Palmers IH. there was Eddies IH, Rocky's IH, Ray's IH so many back in the 70's. My parents used to take me to Palmers and then I grew up to party there, lol. I didn't even know that it was a TX thing until I moved out of state and my mom came to visit as asked "Hey, where are all the ice houses", lol
