I don't really hunt down that direction much, but there is some hunting down there. You will need to do a bit of homework though. There are turkeys, muleys and bandtail pigeons around Palomar mountain which is pretty close to SD (maybe an hour or so). The Imperial Valley is 1.5 - 2 hours away and there is dove, quail, waterfowl and I have heard that run their hound for racoon is the irrigaton canals. There are also a few pheasants in the valley, but I have heard that they are pretty scarce these days. If you like offshore fishing SD is the place in the summer and fall for various tuna species. Anyhow there is some hunting, but you will need to find someone who knows the area.
Good luck and thanks for keeping our country safe.
