“Go Mets!” said Lucy Gold, a little girl from the Upper West Side.

“Mets fans are little people, too — and they’re boys and they’re girls and they’re grandparents,” said Andy Ackerman of the Children’s Museum. “So we have a lot of Mets fans coming to the Children’s Museum to celebrate.”

Inside, there are blue and orange flags marking the Mets’ road to the National League pennant. One woman was spotted with her hair dyed the team’s colors.

After tonight the Mets could have two more late-night games before they head back to Citi Field. Some local teachers say they’re going to take it easy on their tired students.

“We’re gonna be flexible tomorrow and I hope everybody is as flexible as I am,” teacher Keri Wade Donohue said.

“I’m supposed to be going to bed at around 10ish. Not happening, ” Mets fan and student  Anthony Leonardo said. “Not until the games over. My homework that can wait too. Once the game’s on the game’s on — I’m clocked in, I’m watching the game.”

The fanfare has Mets faithful checking on airfares to Chicago, where the Amazin’s will face the Cubs in Game 3 of the National League Championship Series on Tuesday night. Last-minute flights Tuesday were going for less than $200.

Mets season ticket holder Ben Weil said he couldn’t pass it up.

“When I saw $140 roundtrip, that became a no-brainer at that point,” he said.

At midday, StubHub had plenty of standing-room tickets at Wrigley Field for the game in the mid-$100 range, with seats for not much more.
