How should I spend my time in Baton Rouge, LA?

I am going to Baton Rouge to look at LSU. My mother and my best friend will be coming with me, but as I look online I see there is nother fun in to do in Baton Rouge. I don't want to see some dumb ship or visit old castles. I would like to do something super entertaining. I saw there is a amusment park call DIXIE LANDIN but it is closed during March, when we will be there. Please note; My friend and I are teenagers. So please suggest something that envolves GOOD TIMES and is fairly enexpensive. Also make it condusive to March weather!!!
