Jacksonville has a lot of places to shoot. There's carbine competitions in north and central Florida as well a IDPA, IPSC, etc. Housing is cheap, I'd stay east of I95 and south of downtown. The beach area is the best IMO, good location if you want a social life, and only like ten it fifteen from downtown or Southside. Rest of Jacksonville Southside area is a mix of suburbia and college town. Rent is cheap, it's a good area, and has plenty of bars, shopping, etc. I believe there a regional office for the Department of Agriculture for your concealed weapons license. No open carry unless you're fishing or hunting or on your way to or from fishing or hunting. You can have a handgun in your car in your glove compartment or center console, it just has to be inside something with a lid or cover and not laying on the seat or sitting under your seat or next to your seat IE not "immediately accessible" and "securely encased". You can put it in a shoe box with the lid closed on the passenger seat if you wanted. You do not need any type of license to carry a gun in your car in this manner. Trunk gun is ok too, rifles, shotguns, etc.
