Going on a prairie dog shooting trip in SD and will be travelling there from NC (at least to IA) in my Porsche 944. Taking 3 rifles (which means the back seat needs to be down) and a bunch of ammo. All the rifles will be cased and locked with the bolts removed and stored separately. Will be staying overnight in Indianapolis, IN and meeting with the rest of my party in Des Moines, IA. My trip will take me through NC, VA, WV, OH, IN, IL(central) and IA. From my reading of the info on the NRA-ILA site, this should satisfy the law but thought I should ask here as well.
