Long drive with 9 people! The 15 wasn't there yet, was it?
My brother lives in Alta Loma and I have a house in Rancho Cucamonga. I remember when Etiwanda, Cucamonga and Alta Loma were combined to form Rancho Cucamonga. The People who live North of Baseline still say they live in Alta Loma though. It always was a nicer area.It is actually the San Bernardino mountains there.
When did you leave there?
No Interstate 15, Foothill Blvd was Highway 66. Baseline was the dividing line between Alta Loma and Cucamonga. My Dad moved the family from Wisconsin in 1953 and built our house on the end of Hermosa among citrus orchards and egg ranches. All of us kids when to Alta Loma Elementary, K through 8th grade. The school was by the train depot, post office, and American Can Company. My parents moved back to Wisconsin in 1970. I left Alta Loma shortly after.
There was a small piece of San Bernardino National Forest above us - the east end of the San Gabriel Mountains. The San Andreas Fault runs up Cajon Pass and is the boundary between the San Bernardino Mtns to the east and the San Gabriels to the west.
I spent most my youth up Deer Canyon, Day Canyon, and Cucamonga Canyon.
Lots of memories down there back when it was rural. It's been a long time since we've been back.
