I grew up in the Los Angeles area in the 40's, moved to Compton, CA for 
a few years, then to Cucamonga, CA in 1952. I do not remember that my 
family practiced the Posada tradition, but seem to remember that we may 
have attended a "Posada" on Olvera Street during the Christmas season. 
I remember attending "Posadas" in Mexico City in the early 60's. I love 
the concept of the posada, but it always seemed like a lot of work to 
put it into practice for just my family.
Now - how about "La Pastorela"? Is this strictly a tradition in the 
southhwest? Again, this is not a tradition that was a part of my family.
How about yours?
Y'all have a good day. Take care.
