Dang it Gianni why do you make me choose? Haha.
Got to say coasts if I must pick.
While I like both, I like mountains best.
Is this a trick question?
<(I grew up on the north coast of Oregon.)
I like both equally.
When I read the question, I immediately thought of the Oregon Coast, and the way the mountains drop straight to the ocean.
I love in the mountains, I'm only an hour from the ocean though.
