CENTER TWP — Lydia Houllion thought she was just going to the drive-in Saturday night.

But that's not what her boyfriend, Sam Helbling, had in mind when the couple arrived at the Starlight Drive-In on Route 8 just before 7 that night.

Helbling of Plum, Pa., said the couple's first date was at that drive-in in July 2015, and after only knowing her for a year and a half, Helbling was ready to ask for Houllion, from Worthington, Pa., to marry him.

Armed with a homemade video of the two of them, Helbling approached the drive-in owners, John and Beth Manson, with his idea: to use the big screens to propose to Houllion.

A little before 7 p.m., Helbling excused himself to go to the concession stand, all part of the plan.

Houllion, in the back of Helbling's pick-up truck, was left alone to watch a four-minute video that Helbling had put together of the best moments the couple has shared.

Eventually, Helbling walked back to the truck and proposed and, of course, she said yes.

But that was no easy task. Houllion said she was so choked up she could barely answer.

"I was crying so hard I couldn't even answer. I was so happy, so surprised. It was perfect," she said. "I had to choke it out because I had been crying so hard.

But Helbling, frankly, was not worried about that Houllion saying no.

On Friday afternoon, before the proposal, Helbling said: “I'm not real scared of getting the wrong answer,” he said. “I feel pretty confident in myself... Not one bit (worried). If I was, I wouldn't do it.”
