Great story you guys! So cool you could share such an experience together! And I'm glad it all worked out well...
I always carry a med kit with me (and I've had to use it in the filed from time to time over the years). But butterfly bandages or steri-strips would have worked well on that wound. I also carry a small amount of tincture of benzoin which really helps bandages stick to your skin in places where bandages don't like to stick. Literally, having a good, simple med kit can be a life saver!
