I'm going to assemble a first aid kit that will travel along with me out of town and generally remain in my hotel room. While there are plenty of kits you can buy, it's likely these are over-priced and/or inadequate in many ways. I haven't taken the time or effort to study up on any of this, so I'm hoping for some suggestions that come from experience or professional medical knowledge.
Aside to Ryan: You can skip the "stopping a nosebleed by applying a tourniquet to the neck" routine. I've heard it and the humor has worn off.
