I've never had a PH carry a kit in the field. It's always back at the vehicle. I always carry with me a small day pack that has a couple of band aids, gauze pads, anti bacterial ointment, adhesive tape, small bottle of eye wash, and a large swiss army knife.

For those of you who are prone to getting blisters (like me), a few years ago, I started putting a wrap of adhesive tape over the two spots on my left foot that always seem to raise blisters. I do this the morning the hunt starts. Since I started doing this, I've not had a blister since.

One other piece of advise regarding blisters: while you are walking, and you feel a "hot spot" starting on your foot, that is the time to immediately stop and apply a piece of adhesive tape over the hot spot. This will prevent the blister from getting worse, and will make walking a lot more comfortable, as your sock will now rub over the tape, and not your skin.
