The market is new this summer and is open every Sunday at the drive-in on the Hermon-Bangor line.
The drive-in's general manager said drive-in flea markets are big in the south and they wanted to put the lot to use in the daytime when movies aren't playing.
He said they have about 40 vendors right now, with goods ranging in price from fifty cents to a few hundred dollars.
They've been getting new vendors every week.
"It's been a lot of fun - from the people out shopping to the vendors, the vendors are having a lot of fun talking to each other. It's definitely a community thing," General Manager Steven Look said.
The flea market also has food available.
Anyone interested in becoming a vendor should send the drive-in an email or stop by.
