Since I' ve been elk hunting before(this is gonna be my first) I can' t help on what to pack in with you. As far as the 24 mile ride in, wear Wrangler 13mwz jeans. They have the thick seam on the outside of the leg. Any jeans that have that thick seam on the inside will turn the insides of your legs into hamburger no matter how many pairs of long johns you have on. When I was growing up, my folks had a cattle ranch in NE, I made the mistake of wearing Levis one day riding. After about 8 hours in the saddle my legs were bleeding. To this day I refuse to wear any jean like that. I haven' t been on a horse in 6 years and my legs hurt just thinking about it. Good luck on your hunt!
