We use to visit my grandmother in Altadena (we are talking up into the 1960's here). And I was AHS Class of '72, but lived in the Midwick Tract (the other side of the freeway). Use to hit the mountains from the top of Lake Blvd in Pasadena.
But I would like to see The Alhambra one of these days if I ever get to Europe (I have a ton of other places I want to see before the European mainland -- Iceland, more of Australia, Norway, Scotland, etc etc! LOL! But there is also a lifetime worth of places here in the western USA that I want to see or return to, also!
