"I learned that the BOOseum at Children’s Museum Houston offers daily trick-or-treating for little goblins and mini superheroes plus interactive activities like searching for goodies and goo and experimenting with mad scientist concoctions; general admission is $17, the museum opens at 9 a.m. Tue–Sat, and trick-or-treating begins at 3 p.m. on weekdays and is available all day on weekends during the event." - Brittany Britto Garley
