First off -- wish you two the best of luck.
Your daily practice is the best thing you can do to prepare because once the adrenalin kicks in during your hunt the rest has to be second nature. If you have watched any of the bear'n down videos you've had some great advice already and some great tips. If not then I'd say order several today LOL. And no I don't have any connection with this place.
Look forward to your reporting back in as how the hunt progresses.
