GUILDERLAND — Trick or Treat Street has become a Guilderland tradition.

“It’s an extravaganza and we haven’t raised the price,” said Ann-Marie McManus, co-advisor for the Class of 2010.

For $5, a child can trick-or-treat around the school, play carnival games, see a magician perform, hear scary stories, do a cake walk, learn about safety from a dog named McGruff, sing along, bounce on a bouncety-bounce, or have her face painted.

Adults get in for free.

The event, a fund-raiser for the Class of 2010, runs at Guilderland High School from 4 to 7:30 p.m. on Saturday, Oct. 24.

The class of 2006, which, like ’10, was advised by social studies teachers McManus and Jim Corona, held the first Trick-or-Treat Street in 2004. McManus came up with the idea then as something she remembered from her Long Island high school.

The Guilderland event was shaped by the Class of 2006 and has grown ever since.

“Every elementary student will get a flyer in their backpack mail,” said McManus, noting how grateful she is for the support. The flyer says the $5 admission “comes with a game card, candy, and tons of fun!”

Many of the visitors will be younger than school age, she said, noting her 2-year-old son will attend, dressed as a tiger.

The kids running the haunted house are aware of what kids at each age level can handle.  “They bring them in groups and ask, ‘Do you want really scary or a little scary?’” said McManus.

Different clubs and organizations — from the international club to the drama club — will fill the classrooms, where costumed kids will offer treats and perhaps some tricks to those who come knocking at their door.

“They like to dress up and be part of the Halloween fun,” said McManus.

Librarian Melissa Gergen will tell scary stories, and the class has hired a magician who will perform in the auditorium as part of the $5 admission price.

Pizza, popcorn, and cotton candy will be available, and visitors can pay to have Lifetouch Studio take a professional portrait of them in costume.

Jonathan Ouckama, a reading teacher, will lead a sing-along of popular kids’ songs, and the Guilderland Police will bring their puppet, McGruff the Safety Dog. He’ll talk to kids about safe trick-or-treating.

“The gym will be filled with carnival events,” said McManus.

This includes tossing games, a bouncety-bounce, and a miniature golf course.

“They all get prizes,” said McManus. “It’s a full building-wide venture.”

Visitors will have a chance to paint pumpkins and to watch a clown making animal balloons. Kids can also participate in a cakewalk, which works sort of like musical chairs, McManus explained. “The last one standing wins a cake,” she said.

McManus expects 700 to 800 children will attend. “The building will be filled,” she said.

The money will go to the senior class. “This year, we would like to cut the ticket prices for the ball,” said McManus.  Last year, tickets cost $45, which can be hard to come by in tough times, she said.

The money also pays for a senior picnic on the last day of school, and for flowers on graduation day as well as for a gift to the school from the class.

The class of 2006, which started Trick or Treat Street had money left over to give to school organizations, McManus said.  “The gift was furniture for the lounge, and it’s still there,” she said.
