Park at Palm Ave Trolley Station Parking Lot

Per @SanchoRG, this parking is the most viable parking option as it's free, safe, and still close to the border, which was within 4 stops from San Ysidro PedEast. I actually didn't even know this option existed until he mentioned to me and especially since they racked up the parking fee at the border, I decided to give it a try. Why not, right? Plus, I didn't wanna start off my long craved Zona Norte visit with ridiculously high parking fee (I know you pay when you leave, but still it already kinda feels demoralizing when you know you are getting ripped off and you are still doing it anyways). So I arrived at Palm Ave Trolley Station around 5:30 pm and I already see about 40~50 cars parked in the parking lot, so I definitely felt safe parking there. I came back last night to the parking lot around 1am and my car was fine. I think more mongers should just stop getting ripped off by these border parking lots and use this option. Definitely worth it.
