I hear dreadful experiences of conventions in the 1950s of 5 plus days conventions.
Imagine its 95degrees in the shade sitting there on bleachers. Having to camp out in crowded campgrounds with no a/c,, mosquitos,, flies & outhouses.
I remember growing up in the 1980s of the convention starting on Thursday afternoon & lasting all weekend in some arena all day on plastic moulded seats. No a/c & crowded concourses.
