Barrent was a little disappointed, even though he realized that there would be no virgin wilderness so near a starport. In fact, on a planet as old and as highly developed as Earth, there was probably no virgin land at all, except what had been preserved in national forests.

The sun was low on the horizon, and there was a chill in the long shadows thrown across the forest floor. Barrent found a comfortable spot under a gigantic oak, arranged leaves for a bed, and lay down. He had a great deal to think about. Why, for example, hadn't guards been posted at Earth's most important contact point, an interstellar terminus? Did security measures start later at the towns and cities? Or was he already under some sort of surveillance, some infinitely subtle spy system that followed his every movement and apprehended him only when ready? Or was that too fanciful? Could it be that—?

"Good evening," a voice said, close to his right ear.

Barrent flung himself away from the voice in a spasm of nervous reaction, his hand diving for his needlebeam.

"And a very pleasant evening it is," the voice continued, "here in Forestdale National Park. The temperature is seventy-eight point two degrees Fahrenheit, humidity 23 per cent, barometer steady at twenty-nine point nine. Old campers, I'm sure, already recognize my voice. For the new nature-lovers among you, let me introduce myself. I am Oaky, your friendly oak tree. I'd like to welcome all of you, old and new, to your friendly national forest."

Sitting upright in the gathering darkness, Barrent peered around, wondering what kind of a trick this was. The voice really did seem to come from the giant oak tree.

"The enjoyment of nature," said Oaky, "is now easy and convenient for everyone. You can enjoy complete seclusion and still be no more than a ten-minute walk from public transportation. For those who do not desire seclusion, we have guided tours at nominal cost through these ancient glades. Remember to tell your friends about your friendly national park. The full facilities of this park are waiting for all lovers of the great outdoors."

A panel in the tree opened. Out slid a bedroll, a Thermos bottle, and a box supper.

"I wish you a pleasant evening," said Oaky, "amid the wild splendor of nature's wonderland. And now the National Symphony Orchestra under the direction of Otter Krug brings you 'The Upland Glades,' by Ernesto Nestrichala, recorded by the National North American Broadcasting Company. This is your friendly oak tree signing off."

Music emanated from several hidden speakers. Barrent scratched his head; then, deciding to take matters as they came, he ate the food, drank coffee from the Thermos, unrolled the bedroll, and lay down.
