The wizard in plus-fours accompanied them toward the gate to the campsite. He looked exhausted: His chin was blue with stubble and there were deep purple shadows under his eyes. Once out of earshot of Mr. Roberts, he muttered to Mr. Weasley, “Been having a lot of trouble with him. Needs a Memory Charm ten times a day to keep him happy. And Ludo Bagman’s not helping. Trotting around talking about Bludgers and Quaffles at the top of his voice, not a worry about anti-Muggle security. Blimey, I’ll be glad when this is over. See you later, Arthur.”

He Disapparated.

“I thought Mr. Bagman was Head of Magical Games and Sports,” said Ginny, looking surprised. “He should know better than to talk about Bludgers near Muggles, shouldn’t he?”

“He should,” said Mr. Weasley, smiling, and leading them through the gates into the campsite, “but Ludo’s always been a bit . . . well . . . lax about security. You couldn’t wish for a more enthusiastic head of the sports department though. He played Quidditch for England himself, you know. And he was the best Beater the Wimbourne Wasps ever had.”

They trudged up the misty field between long rows of tents. Most looked almost ordinary; their owners had clearly tried to make them as Muggle-like as possible, but had slipped up by adding chimneys, or bellpulls, or weather vanes. However, here and there was a tent so obviously magical that Harry could hardly be surprised that Mr. Roberts was getting suspicious. Halfway up the field stood an extravagant confection of striped silk like a miniature palace, with several live peacocks tethered at the entrance. A little farther on they passed a tent that had three floors and several turrets; and a short way beyond that was a tent that had a front garden attached, complete with birdbath, sundial, and fountain.

“Always the same,” said Mr. Weasley, smiling. “We can’t resist showing off when we get together. Ah, here we are, look, this is us.”

They had reached the very edge of the wood at the top of the field, and here was an empty space, with a small sign hammered into the ground that read WEEZLY.

“Couldn’t have a better spot!” said Mr. Weasley happily. “The field is just on the other side of the wood there, we’re as close as we could be.” He hoisted his backpack from his shoulders. “Right,” he said excitedly, “no magic allowed, strictly speaking, not when we’re out in these numbers on Muggle land. We’ll be putting these tents up by hand! Shouldn’t be too difficult . . . Muggles do it all the time . . . Here, Harry, where do you reckon we should start?”
