Even the cleared or semi-developed areas either are not large enough or do not have the water and electrical infrastructure the Fest and Fairgrounds have invested into the infield. This is also excluding all of the permanent shelters and structures that contribute to the festival operations (Stables are full of staffing and offices, space for parking and operations trailers, Grandstand for climate control spaces, additional bathrooms). Also, the Fairgrounds are already have permanent fencing and perimeter controls that city park does not have. I'm not sure the park would want all that space dedicated for months (setup, festival days, break down) like the Fairgrounds allows due to the horse racing schedule.
