Back yard Sweet Sixteen party?

Having it in the backyard definitely sounds fun! There is no need for alcohol at a Sweet SIXTEEN, do don't listen to that. The pool table, darts & video games will definitely be fun! My suggestion is maybe to invite your REAL friends, not necessarily people that you want to impress. The "popular" girls will probably be bores anyway ;) Just get some snacks, drinks & play some music, maybe get some cute lanterns.. sounds like a blast!! :)
