To over simplify to 2 sides:
side 1) You should do your pump the way I want you to do it
side 2) You should do your pump the way you want to do it
I'm all for preserving history, but let's face it, as much as we love old gas stations and gas pumps, they aren't the liberty bell or the Spirit of St. Louis.
If 1 out of a thousand Wayne 60's are made to look like a space ship, it's not the end of the world or completely obscuring or rewriting history.
If it gets up to 5 out of a thousand, then we should get the government involved to make at least 3 of those 5 conform.
