Things are looking a little shady in Hannibal. And that's a good thing.

In honor of Arbor Day, fourth graders from area schools will plant 17 trees in downtown's Central Park on Friday, April 27. Hannibal's Tree Board and the Parks and Recreation Department are sponsoring the tree planting. Students from Holy Family, St John's and Eugene Field will assist in the planting. Central Park is also featuring a Storybook Trial. The pages from the book "Arbor Day Square" are reprinted on signs that students can read as they walk the trail.

Here's a fun fact. The first Arbor Day happened way back in 1594 in a little Spanish village. The first Arbor Day in America took place in 1872 when one million trees were planted in Nebraska.
