I'm a California resident that is going to take a trip to IL and I was thinking about going to a range with some of my friends that live there. I already know that I can, with my CA driver's license, rent and fire @ a range. My question is: I am allowed to sponsor one person? Can this person be one of the IL residents? Or do they need to be sponsored by someone with a FOID card? Please give me any other information I should know before trying to bring a small group of people (about 3+) to a range. Thanks.
