My sister is getting married soon and she called me today and said... So for my BP I think im just going to have some girls over and play some boardgames and stuff... My mom thinks we should plan something really fun to suprise her. She LOVES being center of attention so I was confused when she just wanted to play boardgames. BUT Im the only one who is under 21

So we cant go out to bars... so any ideas for a great time without bars?
