I'm trying to understand what I'm missing.

I might be getting my latitude and longitude confused- but I think that one degree of latitudal (east-west, right?) travel would result in a different distance depending on how far north or south I am? I'm thinking of it like walking around the equator, as opposed to walking in a circle around Santa's house, which is obviously directly on top of the north pole.

But if I travel one degree of longitude, no matter where I am the distance would be the same, right?
