You're not sure what that town contains but a distinct lack of fast food billboards means it's definitely not civilization. The road is a great indication that there is something else the other direction. You hope it's a society that sells egg sandwiches (wishing you had breakfast now, huh?).
As the sun goes over head and falls to the west you're also wishing you had some other form of transportation. Your feet are aching, your back is sore, and your legs aren't sure they want to keep going. Your stomach growls viciously with hunger and you could really use a glass of water. And those lines of smoke aren't any closer. A car or bicycle hasn't passed you all day.

Listen.

What's that?

It sounds like a horse. Make that plural, and maybe a cart It's coming from behind you. Chances are whoever is approaching has already seen you but there's a chance they're not really paying attention and you could still hide. What do you?

I'll duck behind that tree and check them out first.

Hurray! People! I'm sticking my thumb out and hoping for a ride.
