Talk about a road trip. Porter Fox spent months exploring the borderline of the US and Canada from Atlantic to Pacific.

Often you had to look closely to tell which side you were on.

Really the only indication is that when you go through a town,

there's Canadian flags flying on one side

and American flags flying on the other.

Coming up, he tells us what he found along 4,000 miles of the longest national border in the world.

There's a lot you can explore within a couple hours of San Francisco.

Kimberly Lovato shares some of her favorite day trips like the Santa Cruz Beach Boardwalk.

It's so quintessentially California to me with the wooden boardwalk and the old wooden roller coaster.

And Becky Lomax reminds us why America's national parks are always worth another visit.

It's amazing to see the wildlife, to watch wild animals out doing their wild thing.

Let's get out there in the hour ahead.

It's Travel with Rick Steve's.

We're heading for the border on today's travel with Rick Steves, the Canadian border.

While there have been political strains recently, it's still the longest peaceful

national border in the world. Porter Fox found that the border's actually not always so easy to identify,

especially when it runs through lakes and rivers that keep flowing and changing.

Yet a trip along the border can illustrate the westward

pull of both nations and what it means to have a good neighbor. Porter Fox

joins us for a closer look at the Northland in just a bit. We'll also check back with Kimberly Lovato of a hundred things

to do in San Francisco before you die. We'll consider some of the great day trips you can enjoy

within easy reach of the city.
