California. Not to brag about my home state, especially since there are a lot of places here I would never ever go, but there is something for everyone here. If you like mountains, we have the tallest in the continguous 48, and they're mere hours from the ocean. We have busy beaches and empty beaches. We have a couple wine countries. We have deserts and forests. And, there's Disneyland, lol.
Really, There is a lot you can do here and it's all in close proximity to others.
