They rode the boar until sunset, which was about as much as everyone's back ends could take.
Elaine had no idea how many miles they'd covered, but the mountains faded into the distance and were replaced by miles of flat, dry land. The grass and scrub brush got sparser until they were galloping (do boars gallop?) across the desert.
As night fell, the boar came to a stop at a creek bed and snorted. He started drinking the muddy water, then ripped a saguaro cactus out of the ground and chewed it, needles and all.
"This is as far as he'll go," Grover said. "We need to get off while he's eating."
Nobody needed convincing. They slipped off the boar's back while he was busy ripping up cacti.
After its third saguaro and another drink of muddy water, the boar squealed and belched, then whirled around and galloped back toward the east.
"It likes the mountains better," Percy guessed.
"I can't blame it," Thalia said. "Look."
Ahead of them was a two-lane road half covered with sand. On the other side of the road was a cluster of buildings too small to be a town: a boarded-up house, a taco shop, and a white stucco post office with a sign that said GILA CLAW, ARIZONA hanging crooked above the door.
Beyond that was a range of hills ... but then Elaine noticed they weren't regular hills. The countryside was way too flat for that. The hills were enormous mounds of old cars, appliances, and other scrap metal. It was a junkyard that seemed to go on forever.
"Whoa," Elaine said.
"Something tells me we're not going to find a car rental here," Thalia said. She looked at Grover. "I don't suppose you got another wild boar up your sleeve?"
Grover was sniffing the wind, looking nervous. He fished out his acorns and threw them into the sand, then played his pipes. They rearranged themselves in a pattern that made no sense to Elaine, but Grover looked concerned.
"That's us," he said. "Those six nuts right there."
"Which one is me?" Percy asked.
"The little deformed one," Zoe suggested.
"Oh, shut up."
"That cluster right there," Grover said, pointing to the left, "that's trouble."
"A monster?" Elaine asked.
Grover looked uneasy. "I don't smell anything, which doesn't make sense. But the acorns don't lie. Our next challenge ..."
He pointed straight toward the junkyard. With the sunlight almost gone now, the hills of metal looked like something on an alien planet.
They decided to camp for the night and try the junkyard in the morning. No one wanted to go Dumpster-diving in the dark.
Zoe and Bianca produced six sleeping bags and foam mattresses out of their backpacks. Elaine didn't know how they did it, because the packs were tiny, but they must've been enchanted to hold so much stuff. She'd noticed their bows and quivers were also magic. She never really thought about it, but when the Hunters needed them, they just appeared slung over their backs. And when they didn't, they were gone. She would have to remember to ask for one of those the next chance she got.
