Do you have a little princess, superhero, goblin or ghoul who loves science and technology? Gather up your trick-or-treat enthusiasts and join the City of Tuscaloosa for Tech or Treat at the Gateway on Thursday, October 24 from 6 to 8 p.m. Similar to "trunk-or-treat," at the City’s Tech or Treat, families go from table to table collecting candy. At each table, children are introduced to science, technology, engineering, art, and math (STEAM) opportunities by interacting with City departments and community organizations. Tech or Treat is free and open to all ages. Children must be accompanied by an adult.
