Officials said the decision was made, "following a complete inspection of the grounds and rides," according to a post on the fair website.
However, some events were postponed or canceled.
• Thoroughbred horse racing and simulcast racing are canceled for Sunday.
• Also canceled is the 4-H Jr. Western Horse Show. It will not be re-scheduled.
• All livestock shows are on schedule, but a livestock sale is postponed until Sept. 4.
The fair is scheduled to run until 10 p.m. on Sunday.
Saturday as Hurricane Irene crept up the East Coast, what should have been a festive opening weekend became a bit more stressful for organizers of the Maryland State Fair.
Officials closed the fair's midway rides and games at 3 p.m. on Saturday, and the rest of the fairgrounds closed for the day at 6:30 p.m.
Max Mosner, president of the State Fair, said discussions about what to do should the storm hit had long been long under way.
"We've had an interesting couple of weeks leading up to the fair, and even more so the last few days," Mosner said Friday.
Plans were already in place to protect the carnival equipment and the animals.
"We rearranged the livestock show schedules so that most could show their animals and take them home," Cashman said on Saturday. "There are beef cattle and boar goat shows tomorrow (Sunday) that some exhibitors wanted to stay for. Two or three exhibitors are from the eastern shore and felt safer staying here with their animals than taking them home."
