September is in full swing and fall is right around the corner. But while the morning air begins to turn crisp, some Howard County businesses are holding onto summer for a little longer.

From the End of Summer bash at K-9 & Coffee to another Wine Bin summer movie night, here are some things to do in the county for the week ending Sept. 11.

Trivia at Ellicott Distilling Co.

Thursday nights, weekly

Happy hour, trivia, karaoke, oh my! Ellicott Distilling Co. has it all on Thursdays. Trivia starts around 8 p.m. Go a bit earlier to catch the end of happy hour (it runs until 7 p.m.) and snag a seat. If you would rather sing the night away, karaoke starts at 9 p.m.

Also, first responders, military personnel and teachers receive a 10% discount.

Women’s self-defense class

5:30 p.m. to 7:30 p.m., Friday

Howard County women all learn essential self-defense techniques at Watchdog Krav Maga on Friday evening. The event is meant to empower women as they learn how to protect themselves and gain confidence in any situation.

Friday’s free class is hosted by CareFirst Engagement Center.

Grandparents Day in Howard County

1 p.m. to 5 p.m., Saturday and Sunday

Celebrate Grandparents Day, a national holiday typically observed on the Sunday after Labor Day, all weekend long at the Ellicott Mills Children’s Museum. Families can tour the museum, play games and participate in activities. There will also be a photo station, and grandchildren with their grandparents can enjoy cupcakes. The free event is from 1 p.m. to 5 p.m. both Saturday and Sunday.

The Ellicott Mills Children’s Museum, located in Ellicott City, is a hands-on educational center that teaches children about the history and culture of people who lived and worked in a 19th century mill town.

Summer movie night at The Wine Bin

Starts at 8 p.m. Saturday

In the iconic film “Field of Dreams,” Kevin Costner’s character Ray Kinsella hears a voice out in the Iowa cornfields saying, “If you build it, he will come.” His character takes that to mean he should build a baseball field in his cornfield. He does — and then the rest, well, you’ll have to see for yourself.

Watch “Field of Dreams” on Saturday night at The Wine Bin. There are wine tastings and live music before the movie is shown. The Wine Bin’s parking lot closes 90 minutes before the movie begins for the live music. Moviegoers can purchase snacks and libations from the Bin, or can bring takeout from a local restaurant on Main Street.

Can’t make it Saturday? You still have a couple more chances, the summer movie series ends Oct. 5.

End-of-summer party at K-9 & Coffee

11 a.m. to 4 p.m. Saturday

Celebrate the final days of summer at K-9 & Coffee in Glenelg on Saturday. The coffee shop is hosting the summer bash with Your Journey Nursery and Preschool. The event will have bouncy houses, games, music, drink specials, a Caribbean food truck, an open gymnastics gym and more.
