4 Ways to Celebrate Arbor Day
The first Arbor Day took place in Nebraska City, Nebraska, on April 10, 1872. It is estimated that one million trees were planted that day. The idea of a holiday celebrating trees took hold; by the 1920s, every state in the US had passed a law stipulating that Arbor Day be observed on the last Friday in April. In Nebraska, it's observed as a civic holiday. Planting a tree is the most customary way to observe Arbor Day, but there are other ways to celebrate, too.
