I remember those hangers very well. We would be pulling maintenance on 53's and if it was one of those inversion weather days clouds would form up in the tops of the hangers and rain would sometimes fall.
I attended a Marine Corp Birthday Ball in the hangers one year and the rain almost ruined the cake.

When we first lived at El Toro I guess it was early '50's. Santa Ana to Tustin was totally rural with nothing but orange groves. Then groves again and farm roads between LTA and El Toro.
We were back '60-'64 time frame. We lived in Santa Ana and my grandfather in Tustin. Then Dad got base housing on El Toro after my mom died.

This was back in the days when the smog was so bad you never saw Saddleback mountain. It was just a brown haze. I was amazed at how clear the sky was when I went back in the '90's.

Ya gotta remember that back in those days the freeways were still brand spanking new. I-5 from Santa Ana to Pendelton was only 4 lanes. (yea, 2 in each direction)
