Dayton Grotto Gardens is free to visit and is open 24 hours a day. I am not sure how much lighting there is at night. It is located on the property of the Dayton VA Hospital. Permission granted by the American Veteran's Heritage Center.
A series of short field puzzles for you to enjoy as you visit the gardens. All finals are located outside of the hospital, gardens, and cemetery area, but they are all less than 2 miles away. I do NOT recommend finding the finals at night.
A tree dedication. Enjoy the landscaping and flowers around it. Enter the year on the plaque that the tree was dedicated in order to get the coordinates to the container.
