The Festival of Trees, which benefits the Kennedy Krieger Institute, is the second most popular event held at the Maryland State Fairgrounds annually. 

The "Winter Wonderland"-themed fundraiser is on track to be the most-attended event in the program's history. Organizers expect 45,000 people to celebrate the coming of Christmas season this weekend in Timonium. 

The three-day event has grown over the years to more than just a fancy Christmas tree farm, although the decorated trees are still a big draw and a testament to the  creativity of the event's participants. 

Attendees can purchase trees, decorated by various organizations from the Baltimore Ravens and Towson University to local business and non-profits. By Saturday afternoon most of the trees on display had been bought, some for up to $500. 

But the trees themselves are only a partial draw. In recent years the festival has expanded within the Cow Palace on the fairgrounds property to support a full-fledged kiddie carnival. 

The festival runs until Sunday Nov. 28 until 6 p.m. Tickets are $10 for adults and $5 for children, 5 to 12 years old. Seniors and children under 4 are free.
