For the people that don’t know. There are miles of piping inside of a brewery so when they change over they don’t want to put Budweiser in with Bud Light so they came up with Natural Light and call it push beer. It sold so good they had to start making it. Same with Keystone. It was push beer from Coors.
I bet there are still folks around that won't believe anything along those lines.
Like the folks that wouldn't believe that Lucky grocery store bread was exactly the same as Wonder Bread. I made the dough, molded it, put it in pans, baked it, and most importantly changed the dang bags on the wrapping machine, so yeah, I do know.....................but there was always some folks wouldn't believe me and kept buying their overpriced Wonder Bread.
