Oh, and I used to do Azusa Peak, known more colloquially as the Garcia Trail. It was about 1,200ft in 1.25 miles.
Then some jack-wagon teens burned the entire mountainside, and Garcia has been closed for 3 years indefinitely.
Another favorite was The Beast in SCV. 10 mi RT with about 2,400 elev. +/- to Los Pinetos Radio Tower #1.
