I am trying to figure out how I would go about that short hop from Fullerton to Zamperini. It is only 18 or 19 miles, but not that simple - at least for me...

Now I realize I can avoid the class Bravo altogether by staying below 5000ft. Yet there are quite a few Class D transitions and they all "touch" each other. I am not sure how to go about handovers and all of that. It surely must be possible...
Also, I see the option of transitioning the Class C Santa Ana (avoiding Disneyland of course), but that would be quite a long way around. But even then, if I get assigned RWY 24 for takeoff, there pretty much seems no way to avoid the Los Alamitos Class D - and there is really no time to establish two-way radio contact it seems.
Anyway, how would you go about this? What am I missing?
Once I have this one figured out I have a second one that I am struggling with. Let's see...
Thanks so much for any input!
