Fifteen-month-old Lucas Grosswiler helps out his dad with yard work Monday morning at their home in St. Louis. Lucas' father Tim (not pictured) was nearby trimming the lawn. "It's been too hot to do yard work lately so we are trying to get it done early in the morning," Tim said. The lawn mower was not on. "He loves lawnmowers, he has two plastic ones." Tim said of his son.
