Hi lads (and lasses)
First time here. Interesting forum. Very cool.
Drive-ins are still around...although not in their numbers of yester-year. From 4000 at their height in the USA, down to 700 now. You can find them...there's a few websites dedicated to them and show where the open ones are located and even pics and stories of the ones that have gone to the big lot in the sky.
Take a look on Google.com and search 'drive-in' and see what you get.
In Australia, there are even a few opening up from scratch and more re-opening. Some have simply added extra screens to compete with the Godzilla-plexes nearby.
Lots of good memories...but they're not dead yet. It's still warm there in the Northern Hemisphere, right? Look one up and go for a drive. You'll love it if it's your first time and also if you want to re-kindle some old memories of days gone by.
Hope to talk to you guys soon.
