Mike,
Sounds like a fun time. I'm in Escondido. If you get into a bind renting them, you can borrow my Kahtoola KTS trail crampons (great compromise between full crampons and microspikes) if you need them. Or you can borrow my microspikes if you don't have any. I also have actual crampons (I believe they are Grivel G10) I bought a couple years ago but have never used them so I can't tell you much about them, but you're welcome to borrow those too.
All the best.
Mike
