Newbie questions: Rabbit and Squirrel north of Kernville?

[BigFatGuy]

The Mrs. and I are working to become hunters in adulthood, both having grown up in gun-free households in "blue" cities.

We've been once (guided pig hunt), and we'd like to try some small game, Tree squirrel and rabbit being high on the list. (I make a mean gumbo...)

Given how many ways there are to get in trouble when walking around with gun, this is my current plan... please let me know if I'm doing something stupid!

There seems to be good squirrel habitat north of Kernville, along Highway 99 ("Sierra Way"). There's also quite a bit of camping up there.

I figure, we get a campsite, hike away from the marked trails a bit (rules seem to require 150 yards away from campground) to get away from other people, then begin hunting...

We're decent shots, we have lead free ammo, we've got good hiking clothes.

The thing is, that seems too simple! I feel like I must be missing something... and I'd hate to end up a felon or in trouble with DFG.

Am I worrying needlessly? any advice?

Thanks!
