Interact Club members, from left, Brooke Hollister, Francesca Hawkins and Katie Johnson present a check on Tuesday to Brad Nichinson, a member of the Napa Valley Community Foundation. Jason Kelperis, right, is faculty advisor for the Rotary's Interact Club at St. Helena High School, which raised $1,500 for charity on Halloween night. Dressed in costume and seeking "tips for treats," they went door to door asking for charitable donations instead of candy. The money they raised will go to hurricane relief in Puerto Rico, the Napa Valley Community Foundation's fire relief fund, and the What If? Foundation, which serves impoverished kids in Haiti.
