What are your "must haves"?

[aicabsolut]

I ALWAYS pack my Blackberry Curve in a snack-size baggie for the most common thing I will encounter in SoCal -- sweat. On rainy days the snack size baggie it is a "must have". The sandwich baggie is loose enough to operate the keys but the snack size packs in my jersey pocket better.

Even when my cell is in my seat bag, that thing is not 100% waterproof (particularly b/c of the zippers). If I get caught in the rain or something, the phone is soaked. If the phone is in my pocket, it's soaked in sweat. My cell phone always goes in a sealed sandwich bag.
