As thick as you're describing? I don't think so. It's more of a rural accent than a big city accent. Maybe you bumped into a lot of rural transplants while you were there.
I guess I did. I heard it all over the place. Iscariot had it slightly, one of his friends had a heavier one, and the indoor rock-climbing instructor we went to had a really heavy one. I kept making fun of how Iscariot said "about".
