date ideas for coon rapids mn help?

i'm trying to do something different and i need some help.sure the old dinner and movie is alright but i need something fresh.i dont need it to necessarily be specific to this area(i mean there are limitations because it is 1 degree outside lol)but i dont know if i should just ask her what she wants to do or just have it kinda be a surprise.and staying in is good too but my roommate always has people over and that would kill the mood i think.anyone have any ideas?
