Should I give it a shot?

I'm at a cattle show and there is this girl there from Nebraska. I'm from Kansas though. We have to stay in contact because we are helping plan next year's show. She is almost 2 years younger than me. I'm 17 and a half. I have known her for two years. Today her and I went to braums together today and we have been hanging out a lot at the hotel. What should I do, she is so amazing?
