Thirty years ago, a Friday night at the movies involved getting comfortable in a car; it was a mainstay of teenage romance under warm, summer skies.

With theatres now sporting high-tech sound and cushy seating to rival your couch at home, drive-in theatres have all but disappeared. But the relic of baby boomers' childhoods is not yet extinct. A drive-in east of Perth is getting ready for the season.

Nestled between Perth and Smiths Falls, the Port Elmsley Drive-In is now 55 years old. And as it re-opens for the season, there's a nostalgic allure.

"Growing up as a kid I think I took them for granted like everyone else, it never occured to me that they'd disappear or go away," said Dave Bird, who bought the drive-in last year.

Bird's not alone when he says something about the drive-in makes those memories come flooding back.

"Putting on pyjamas, going to the drive-in, falling asleep or pretending to fall asleep in the back to stay up for that second show," said Dan Waters of his drive-in memories.

Others remember the pitfalls of the drive-in.

"I was at a drive-in once but the radio didn't work so we had to go to a real theatre," said Aaron Climan.

But other drive-in theatres are still hanging on. In Ontario, theatres still operate in Woodstock, Peterborough, Pembroke, Lindsay and all across the province. Most only operate through the summer months.
