I'd never thought of doing that - mailing packages back to myself while traveling. Good idea. Saves on weight or trying to cram it in.

What type of camera do you have? And why not use the phone?

The chapel sounded very peaceful. I've been there and to City Lights, but a very very long time ago (1980s). I love San Francisco, such a fun city. And trips by train sound intriguing - I like trains, no motion sickness, you can spread out more, more privacy, and great views.
