bring good orthotic shoes for the death march - it's concrete all the way, and 8 hours of walking on concrete really takes it out of feet.

Stay hydrated - it's a lot more exhausting when dehydrated. Get a good rest the night before traveling, and consider picking up melatonin to help adjust your sleep schedule. Go early to get plenty of rides before the common afternoon thunderstorm.

And above all, you two have fun!
