09.18 AUTUMN AT THE ARBORETUM opens this weekend and runs through Nov. 14. The high temperature for Saturday is 96. That’s fall-like for Dallas, right? The arboretum’s fall features include four walk-through houses made entirely of pumpkins and the Storybook Pumpkin Village. Admission is $10 for adults, $7 for children 3 and older and free for younger kids.
