Halloween is not just a holiday for the Mulkern sisters, it’s a way of life. Samantha, left, and her older sister April attend conventions year round and carefully craft detailed costumes of their favorite TV, movie and book characters to wear at them. The next one they planned to attend was the annual Rock and Shock Horror Movie and Music Convention Friday, Oct. 13 in Worcester, Massachusetts. (Grant McPherson photo) 2p4.jpg
