I grew up in a mix of Newport Beach & Costa Mesa. So Orange County, not LA proper. But for travel purposes, I’d probably catch a nonstop to LAX versus a two-hop to John Wayne.
There will likely be a Facebook group set up - if you are on the FB - that will list who plans on attending.
mmm
There is. Or at least Google assures me there is.
Facebook is something I choose to never deal with. It, and all its works, are anathema, period. I have rather few principles, but this is one I cherish. 
That’s more or less how I feel about a 50th reunion. It’s more convenient to check up on old school acquaintances through sites like Find a Grave or Legacy (how’s that for morbid interest?).
I respect that. My High School class has a FB page too that is set to private and I don’t care to join. The High School itself has an alumni section and a page for each class. That’s an additional place to look.
Figures a guy in your line of work would think that way.
Besides, those folks don’t call you back and bend your ear for hours. Nor flood your inbox w e-mail glurge. 
(How’s “e-mail glurge” for a 2000s-era reference 
)
