Two parts of the Green Line are seen in this video, the first being the street running section in Santee and the other being in Fashion Valley with the elevated section of track! When I was younger I used to go down to San Diego a lot for gymnastics stuff (I didn't compete I just watched my sister do so while I played Pokemon on my Gameboy Advance) and I distinctly remember going to an On The Border in this area and seeing old MTS trolleys gliding past and not thinking too much of them. Nowadays I get excited just to see a glimpse of an SD100 mid-train. Time's weird.
