Hallmark could not create any Fathers Day card as heartfelt as the ones made by the sons and daughters on vacation at Roan Mountain State Park Friday.

McKinna Wiles, 6, from Chattanooga, drew a puppy with pompom earrings on the front of her masterpiece.

She was very proud of the cover as well as the portrait she drew inside.

“That’s me, and that’s my daddy,” she said.

She also wrote a short message inside.

“Dear Daddy, You are the best daddy ever. I hope you like your bulldog.”

Elizabeth Gray, 7, from Mason, Tenn., drew a heart on the front of her card.

“It’s going to be a surprise for my daddy,” she said.

On the inside, she drew a rainbow and over it she wrote, “Dear Daddy, I love you so much. I will never stop loving you. Thank you for taking care of me. Happy Dads Day.”

At the adjacent picnic table, Nathan Johnson was being resourceful. By rubbing his crayon over the paper while holding it down, he was able to create a wood grain pattern on his card using the picnic table’s bench.

Antonio Huskey, from Chesapeake, Va., was also eager for the chance to show off his creativity while visiting the park with all his brothers and cousins.

He drew some mountains, which represented the Roan Highlands, behind a stream with the sun peeking out. He also drew a large heart on the front of his card and wrote, “Be natural” inside of it.

“I just wanted to let my dad know that I love him,” Huskey said after he presented the card to his father.

Huskey wanted his card to not just serve as a Fathers Day card, but also a memento from the trip to the park.

Park Ranger Amanda Smithson seemed impressed by all of the creativity displayed that day.

“We try to provide this program for the kids every year,” she said. “It helps kids who are away from home stay connected with their dads.”

A past donation of craft supplies from a member of the community helped make the event possible, Smithson said.
