00:00:09,642 --> 00:00:12,042
On July 31st, 2002,

2
00:00:12,112 --> 00:00:15,843
two teams of travelers
started an epic journey.

3
00:00:15,915 --> 00:00:17,974
Together, the teams
travelled across

4
00:00:18,051 --> 00:00:22,351
the entire length
of the United States of America.

5
00:00:22,422 --> 00:00:26,017
And they did it
traveling only on public land.

6
00:00:29,429 --> 00:00:33,729
Public land is land that is owned
and cared for by the government.

7
00:00:34,868 --> 00:00:38,702
The United States government cares
for over a million square kilometers

8
00:00:38,772 --> 00:00:41,605
of public land.

9
00:00:41,674 --> 00:00:43,471
Some areas
are kept safe

10
00:00:43,543 --> 00:00:47,035
to protect the plants
and animals that live there,

11
00:00:47,113 --> 00:00:52,016
others, simply to preserve the
country's natural and historical
treasures.

12
00:00:54,187 --> 00:00:58,715
Before the journey, both teams
must prepare and pack carefully.

13
00:00:59,759 --> 00:01:03,718
The travelers are volunteers
who care deeply about the public
lands

14
00:01:03,797 --> 00:01:06,095
and want to help people
learn about them.

15
00:01:06,332 --> 00:01:07,424
Just trying to get
everything ready to go

16
00:01:07,500 --> 00:01:10,799
so I know where everything is
on the trip.

17
00:01:10,870 --> 00:01:14,636
It's a great opportunity to share
my passion for the outdoors,

18
00:01:14,707 --> 00:01:17,904
and show people
what our public lands have to offer.

19
00:01:20,046 --> 00:01:23,846
On the Southern border of the
United States, just outside Mexico,

20
00:01:23,917 --> 00:01:27,648
Team South is starting their trek
in the Chihuahuan Desert.

21
00:01:31,991 --> 00:01:34,516
These were once the lands
of the Pueblo people,

22
00:01:34,594 --> 00:01:38,394
who lived here
a thousand years ago.

23
00:01:38,465 --> 00:01:40,899
It also, perhaps,
has the largest number

24
00:01:40,967 --> 00:01:43,401
of different kinds
of animals and plants

25
00:01:43,470 --> 00:01:45,734
of any desert in the world.

26
00:01:50,844 --> 00:01:55,042
Meanwhile, on the northern border
of the U.S., just outside Canada,

27
00:01:55,115 --> 00:01:57,413
Team North
begins their journey

28
00:01:57,484 --> 00:02:02,319
with a hike through the beautiful
forests of Glacier National Park.

29
00:02:02,388 --> 00:02:03,616
High in
the mountains,

30
00:02:03,690 --> 00:02:07,091
the park is home
to over 300 animal species.

31
00:02:11,364 --> 00:02:15,801
Over the 60-day trek,
the teams travel in various ways.

32
00:02:15,869 --> 00:02:18,702
They travel on foot and in cars.

33
00:02:20,507 --> 00:02:23,374
They ride bicycles.

34
00:02:23,443 --> 00:02:25,308
And ride horses.

35
00:02:27,013 --> 00:02:30,676
And ATVs,
all-terrain vehicles.

36
00:02:33,086 --> 00:02:38,683
They also travel over water,
down rivers, and across lakes.

37
00:02:40,760 --> 00:02:43,558
And on the way, they'll stop
and teach people they meet

38
00:02:43,630 --> 00:02:46,861
about the beauty and benefits
of the public lands.

39
00:02:50,403 --> 00:02:51,961
Finally, after two months,

40
00:02:52,038 --> 00:02:55,872
the teams meet
near Salt Lake City, Utah.

41
00:02:55,942 --> 00:02:58,376
Their journey ends here.

42
00:02:58,444 --> 00:03:01,607
The trekkers hope their experiences
will inspire other people

43
00:03:01,681 --> 00:03:04,707
to love and protect
these public lands.
