What could me and my gf do thats different?

Well it seems like every weekend we get tired of going to the mall/movies etc and we wanted to do something different today. Any ideas? I'm only 16 and shes 15 so keep it appropriate. ;) Were not in the mood for just going out and eating or something. We are outgoing. Anything outside is nice. Also keep in mind its already 11:30 in the morning here. I'm in the upstate of south carolina if that helps any. Thanks! :D
