AUSTIN -- Preparations are well underway for this year's Austin City Limits Music Festival.
Stages are being assembled, tents are up and Monday morning the ACL sign went up near the main gate on Barton Springs Road.
The gates open Friday morning to sell-out crowds. Seventy-five thousand people are expected to fill Zilker Park each day of the three-day festival.
Next year the event will expand to two weekends instead of one.
