Tex,
Welcome to SCH....Bummer you can't make the tune-up Saturday….You'd probably learn more at this one event than all the other places combined....The one thing you'll find out about SoCal is the amount of public land versus Texas....And even Colorado to a lesser degree....That said, our public gets hit pretty hard....If you have the opportunity to hunt Mon-Fri, it's like hunting two different spots....Since much of our habitat is thick chaparral...Animals can & will hide right under your nose....As mentioned, A-22 will be your best opportunity for deer locally (D-16/San Diego)
There is a hunting club (MCC) near Lake Henshaw that offers 1000's of primo acreage for turkeys, deer, upland, fishing, & waterfowl.....No outfitters or guides locally that guide for turkeys to my knowledge....You'll have to go way north for that.
As mentioned above....NWTF has monthly meetings to discuss all hunting here in SoCal....Fun time with like minded folks....Get involved, you'll be surprised how much knowledge you'll receive.
Steve
