Slices of Pizza

I like my pizza sliced in triangles. I consider this the proper way to slice a pizza. But about 15 years ago when I moved to Columbus from Mentor (Cleveland area), I noticed that a popular pizza establishment called Donatos was cutting their pizzas in squares or rectangles.

At first I thought it was just their unique deal but other establishments were doing the same thing. It got to the point where I couldn't find a regular sliced pizza pie anywhere!!!

I dealt with the situation but soon grew weary of the crustless pizzas and the constant grabbing for another tiny piece. I sought out pizza joints with the properly sliced zas.

During my visits back home I knew I could get the traditionally sliced pies and began to wonder. Is it a Columbus, Ohio thing to have so many four sided slices of pizzas? Or is it a development whose timing just coincided with my move to Cbus?

Let me know...how are most of the pizza joints slicing pizzas where you reside? If quadrilaterally, how long has this been going on? What do you prefer and why?
