For all you US residents; I'm considering a few things I personally prefer, weather, transit, scenery... i LOVE visiting the east coast and find it super awesome but my heart is on the west coast always.
Tell me why your coast is best
We have a saying here in the mountains of NC: If you don't like the weather, wait ten minutes or move ten feet, it'll change. The rest of the state has a certain level of hot and humid, but not like Louisiana. Fayetteville NC (Fayette-nam) felt hotter because of all the concrete and asphault, but I learned the words 'hot and humid' visiting family in the Louisiana farmlands every summer.
I've only made it out to the west coast twice, once to Vegas (at 17 with my dad. worst time to go but there's still stuff to do) and once to...like outside of Palmdale? Both times it was November, cold and dry and windy as hell.
