Guys: What can a girl say to get your attention?

I was at a rodeo and I saw a really cute cowboy walkin around (i'm a barrel racer) and he was walking around all over where I was. I won barrels and poles so I think he noticed me. I found him on fb, when I add him is there a message I should write or just add him without sayin anything? I saw his bull ride and he got bucked off..so i can't say good ride lol
