What are some good birthday ideas for my 17th later this year? I kind of want to do a murder mystery, so has anyone done one and can tell me a bit about how it went? Last year I did this big scavenger hunt across town, which was loads of fun but it took a long time to score everything. I like parties like these, where the whole thing is a big game, so any other suggestions? Themes are good too.
Also - what's a good/unique/interesting costume for halloween? I'd go as an Aquabat but I already did so for superheros day.
