With hours of voting still to go, Hillsborough County students took posts Tuesday at polling sites to support a half-cent sales surtax for school air conditioners and other capital needs."We're getting smiles," said Eva Hilton, 17, as she and two friends from Sickles High School took a shift at the Maureen Gauzza Regional Library in Westchase."Mostly," added Tate Wymer, 18. "It's been pretty positive."Fellow students, for the most part, support the initiative, they said.Some, perhaps echoing conservative parents, have argued against asking the public to give the school system any more money. And seniors are not always enthusiastic about the tax, as they will be out of the system by the time the tax receipts come in.But, Wymer said, "We're here for future generations."The half-cent tax is expected to add up to $1.3 billion over 10 years. About half will pay for air conditioning overhauls and replacements.A lot more information is here, in What You Need To Know.
