You'll pay through the nose for water at major venues, but security may also ban you from bringing your own in. The solution? Before you head out to the show or game, pack a few different sized bottle caps in your pocket or purse. Assuming you aren't planning on getting violent, this will make it much easier to save your water to sip throughout the event, without worrying about spillage.
This trick works best if you've been to the venue before, and have some idea of what kind of water bottles they use, but you can always bring a handful of them if you aren't sure.
