Tightened regulations on a popular festival site east of Austin has put a damper on possible expansion of events on that site, some of which have budgets of at least $1 million. Joan Havard, an owner of Carson Creek Ranch just outside of Austin, said promoters with Insomniac Events and C3 Presents, now owned in part by industry giant Live Nation, have scouted the 60-acre property this year to possibly hold large-multi-day festivals for 30,000 to 40,000 people.
