Welcome to the forum srh,
Do you have your hunter safety ed certificate, annual license and upland bird stamp? Make sure you know the regs. There are some "sticky" threads at the top of the list of threads in the newbie den that have good info. I suggest you read them thoroughly. Hunting is legal in CNF and on BLM land, with some restrictions (archery only in Laguna Rec Area, for example). You can go online to order printed maps from them, or if you have a smart phone and $30 to spare per year, download OnX map app and order the CA premium subscription. You get a free 7 day trial and pretty much everyone makes the purchase. Take time to use the search function on this site. It's very useful; pretty much any question you think of will have been asked and answered already. If you read the thread and still have a question, post it and the thread becomes active again.
Happy hunting!
