Allegheny still looks odd to me and I've live here for ages. Pennsylvania no longer looks odd since I see it all the time. I did have to inform my newspaper teacher in high school that we weren't being lazy when we quoted someone as saying "PA" cause, you know, we are weird and actually refer to PA as PA and not Pennsylvania when we talk...Pennsylvania.
...I don't think I've written that word out for ages. It looks so bizarre again.
