I'm leaving on vacation from Indiana and plan on going to Washingto D.C., then heading up to Gettysburg Pa. and then up to Niagra Falls Ny. I had a friend tell me it's ok to travel through states that don't honor my Indiana cc permit as long as I don't stay the night there. I'm a little foggy on this legal stuff so some good advice would help. I don't plan on carrying but would like to have it with me at least. What ya think?
