Harrybrooke Park and Harden House Museum in New Milford will present an end-of-summer screening of “The Wizard of Oz” Sept. 1 and a new event, Still River Jam, Sept. 9.

The movie will be screened Sept. 1 at dark, about 8 p.m., while the “Still River Jam” will run Sept. 9 from 2 to 6 p.m. at the park off Still River Drive.

A rain date of Sept. 8 is planned for the movie, which is co-sponsored by Bank Street Theater and The Hobby Hangout.

“We have such a great venue for this sort of event,” said Billy Buckbee, executive director.

“Since I got the news I’ve been singing ‘We’re out of the woods, we’re out of the woods’ but we aren’t!,” he quipped.

“This event is among the trees, but no apples will be thrown. It’s just a great way to say thank you for all of the support all year long,” Buckbee said.

Guests are invited to dress as their favorite “Wizard of Oz” character.

Donations are welcome but not required.

The event will be capped at 300 participants; no tickets may be purchased in advance.

The Still River Jam will feature music by country tribute band Shot Down, food and drinks, and vendors.

“This is a brand new event for the park so we hope people stop by and check it out,” Buckbee said.

“Live music in a family- friendly outdoor environment is not easy to find, and we felt a late summer afternoon was ideal.”

Tickets are $20 per person. Tickets ordered in advance will include a beverage ticket.
