Pretend it's the day your permit says to start - How do you get from San Diego to the terminus? The bus runs a few times a day, drops you off at the store, then its ~2 mi S to the end. Do people use Uber to get there on demand? Is there a trail angel shuttle? I've heard you don't want to get there the night before and camp on the border. What's the best way to get a dawn start on Day1?
