Texas Fair is in OCTOBER but will post this for next year's Fair.....
Southwest of downtown Dallas about 20 miles is Joe Poole Lake situated between the towns of Grand Prairie and Cedar Hill. On the Grand Prairie side are Corps of Engineer parks. On the Cedar Hill side is Cedar Hill State Park. The Corp Park is nice but no sewer hookups. The state park has few, if any, sewer hookups. The corp park is near HWY 360 just south of I20. Cedar Hill SP is south on FM1382 from I20. You will have 30amp, water, and dump stations at both the Corp and the State Park. I dont know about 50amp service.
As others have said, inside the State Fairgrounds is relatively safe with lots of police offiers. DO NOT park in any private parking outside the fairgrounds property. The fair property is surrounded by the worst parts of Dallas with extremely high violent crime rates. I grew up in Grand Prairie and went to the State fair often from the 70's into the 90's, so I knows of what I speak.
