Bikers are gathering for this year's Bulldog Bash in Warwickshire.
The annual bash at Long Marston, near Stratford-upon-Avon, features rock and metal acts and a quarter-mile drag racing strip.
Fewer road closures are planned by police, who have opposed staging the event in the past amid fears over possible violence.
Assistant Chief Constable Bill Holland said he recognised that past road closures inconvenienced residents.
The 24th Bulldog Bash starts on Thursday and ends on Sunday.
