Finish maps with labels and correct coordinates

With the projection I've chosen, you can't have lat and long on the axes because the US is curved (thanks to the projection...and, I mean, reality). I could do another projection, but then it's not as aesthetically pleasing because it stretches and squeezes diff parts of the US, and the projection I'm currently using is the one used most often (in my experience) when doing a simple figure of the US in articles. So I'm thinking to just do what other people have done, and not include lat/long coords.
