TETNA’s Halloween Trick or Treat nighttime event is back and better than ever! The Trick or Treat event is from 6:30 to 8:30 p.m. Saturday, Oct. 30 for TETNA-registered members. The trick-or-treating is for children ages 14 and younger. The whole family is welcome to join the fun, and each group of children should be accompanied by at least one adult. You must register to be an official event participant – whether your little goblins will be trick-or-treating or you will be handing out candy (or both).
