On your marks, get set, get muddy.
Folks can wallow while in wet soil during the second annual San Diego Mud Day Saturday, June 29 from 10 a.m. to 1:30 p.m. at Crown Point Park at Crown Point and Moorland drives.
The free event is open to the public and whole families, said City spokesperson Ombretta Di Dio. Anyone of any age can participate in the child-oriented festivities.
San Diego Mud Day will feature nature crafts, a mud obstacle course, a mud pit, nature crafts (such as pine cone bird feeders and making s’mores from homemade solar ovens), fort building, food trucks and Dr. Bronner’s Magical Foam Experience, which involves dispersing snow-appearing biodegradable soap. 
The experience was created to honor the late Jim Bronner, son of Emanuel Bronner, who invented industry-standard fire-fighting foam concentrate in the 1980s, later adapted to make artificial snow for Hollywood sets and for entertaining children in backyards.
Children will also have the chance to learn about nature from park rangers who will bring snakes and organize a nature scavenger hunt.
Sturdy shoes, towels and a change of clothes are recommended.
The idea behind Mud Day is to get children closer to nature and inspire them to “get dirty” while connecting with the earth.
International Mud Day traces its origins to 2009 and the World Forum for Early Childhood Care and Education in Belfast, where two members of the Nature Action Collaborative for Children, Gillian McAuliffe from Western Australia and Bishnu Bhatta from Nepal, first discussed the concept.
