Kent Harfst, of the Webster City Parks & Rec Commission, says the students planted trees along Brewer Creek.Harfst says the planting of those 700 trees was a nice way for students to put a positive spin on the dark memories of the date.Tomorrow, 2000 trees will be planted in Webster City as part of Earth Day.
