I grew up hunting deer in hills around Hemet CA. I don't think there is much of a migration for these deer. We used to find sheds right where we were hunting in Sept and Oct. We used to hunt a spot that was high in elevation also. We would drive up there in 2 feet of snow to look at bucks in Dec and January. They never seemed to leave. I think you would have more fun chasing turkeys in your area. I hear that they are starting to get good populations of birds in northern San Diego county. If you could find a 3 point shed with an 8in main beam, it would be a big one for that area! lol!
