Welcome to LA - 10-lane freeways all round!

LA's Union Station.

My first Amtrak train - of many.

After an overnight trip, I ended up in Flagstaff, Arizona.

Nowadays this road is fronted by gas stations and drive-thru ATMs.

The reason I was there was to come here!

The Grand Canyon: fantastic.

Grasping the scale of it is really hard.

If you're having difficulty, imagine fitting your hometown in that hole.

Showing the different layers of rock. Incredible!

Back at the Pacific coastline, around Santa Barbara.

Further up, near San Luis Obispo.

Recognise this prison?

Lombard Street's rather twisty...

...the twistiest in the world, in fact!

Yes, I'm in San Francisco. Here's the end of the Bay Bridge.

The Coit Tower, illuminated at night.

One of Frisco's many ridiculously steep streets.

A famous bridge... can you guess what it is yet?

That's right - I wasn't sure whether to be reassured or panicked reading this!

Thick fog...

A few days later, the fog finall cleared! Sadly I was on the other side of the Bay.

Starbucks - that can only mean one thing.

I'm in Seattle!
