Here's the situation. I have a 7 year old son who I share custody with his mother. His mother lives about an hour from me, but in Illinois. I live in Missouri. What is the deal when it comes to residency with buying permits. I was going to take him on the youth deer hunt this year. Would I need a out of state tag? I would just like to know my options. I wouldn't think it would matter to much as a youth, but when he is a little older it might. Any input would be great.
