(NECN: Lauren Collins, Hampton Beach, N.H.) - It began with a tweet, sent Monday by Fitchburg High junior Courtney Koch.
"I was like, 'Hey it's gonna be 90, we should all skip school.' And then everyone re-tweeted it and I was like 'Yes it's gonna happen!' And here we are. It happened," she says.
Hundreds of high school and college students from Massachusetts and New Hampshire packed Hampton Beach Friday.
Fitchburg High sophomore Allison Lussier swears, "I woke up sick. I was very sick when I woke up. Very sick."
Her twin sister, Emily, knows exactly the ailment.
"I definitely already have senioritis as a sophomore, it's pretty bad," she says.
Some were taking part in the rogue tradition of senior skip day. But this crowd is mostly juniors and sophomores. While the seniors at Fitchburg High were taking finals on Friday, these sunbathers will be grueling through the SATs Saturday.
"I'd be too stressed at school right now. I wouldn't want to take 'em tomorrow. Now I'm going to be excited to take them tomorrow," Jessica Falconer says.
And, no, she doesn't really believe that.
Ahh, the long awaited days of summer and all the business that goes with them.
"People don't eat as much when it's really hot out," says vendor Ramon Hashem, "but we'll sell a lot of lemonade."
Lemonade served up by Sara Corbett, who sat in the rain and looked at an empty beach all last weekend.
"People are showing up, having a good time. Hampton Beach, it's summer!"
Almost. Three to four more weeks of school left for most students. But on this Friday, a perfect preview of what's to come.
Junior Tony Duong says, "We're here to have fun. We're responsible, we're kids, we're here to have fun!"
