Beautiful hilly places in America for wedding?

hi

Since my fiancée’s family lives in the US and his sister can’t really afford to come overseas, we want to get married in the States but I need help! Do you ladies know any beautiful grassy GREEN hilly places for a wedding? If not, what about a nice snowy mountain for wintertime? I heard colorado is nice and it’s winter most of the time over there, right? I have only visited the east coast, I am very familiar with the nation’s capital, the DMV, all the way down to Florida, but not many places after that. I just wanna know more gorgeous locations- if you have a favorite place to vacation for example, or your favorite spot to relax with a lovely view.. or your hometown, any suggestions I would love to hear from you all :)
