During today's ArBOOretum 2009, you'll see owls and squirrels along with monsters and superheroes, so watch out for that bush - it just might be a kid in a really good Halloween costume. Kids will trick-or-treat along nature trails, stopping at education stands along the way to learn about bats, butterflies and other creatures they might encounter in the woods. After trekking through the trees, they can head back to the nature center to decorate pumpkins and enjoy some face-to-face time with pettable animals. There are also carnival games, pony rides and hayrides. Noon to 4 p.m. 4501 Woodway. For information, call 713-681-8433 or visit www.houstonarboretum.org. Free to $15.
