Last summer's popular Downtown Open mini golf course in Huntsville is back for an encore.

Downtown Huntsville Inc. CEO Chad Emerson said the free event has grown to 26 holes -- up from 20 last year -- designed and sponsored by local businesses and organizations.

The fun starts Friday night.

You can bring your own putter and golf balls or borrow them during normal business hours from Harrison Brothers Hardware and Sam & Greg's Pizzeria on the historic Courthouse Square. Don't forget to pick up a scorecard.

If you play all 26 holes in order starting outside Sam & Greg's, you'll loop around the Square, stroll down Washington Street and make a brief stop on Holmes Avenue before doubling back to the closing stretch on Jefferson Street and Clinton Avenue.

Here's a map with the location and sponsor of each hole.

"We've had a huge response," Emerson told AL.com Friday. "People saw how much fun everyone had last year, and the hole sponsors really want to be involved.

"It's free, and putt-putt is something that anyone from two to 92 can play."

Amy Jones, Downtown Huntsville Inc.'s director of special events, said Rocket City Mom is hosting a free "Putt Putt Playdate" for families on Tuesday, June 16. The Huntsville Young Professionals group has scheduled a Putt Putt Crawl for June 18, leaving from Humphrey's Bar & Grill on Washington Street.

The sidewalk mini golf course is a temporary addition to downtown; all the holes will be removed on Sunday, June 28.
