 The National Weather Service is cautioning residents to drink plenty of fluids, stay in air conditioning, and out of the sun. But many locals are still recreating outside just early in the day. John Kasson, who runs a mountain bike camp for children, says it's vital to get his campers off the trail by 10 a.m. We make sure all the kids are hydrated. We encourage them to make sure they have a good breakfast so they're not fatigued. And we just kind of monitor them throughout the day and make sure that they're staying safe.
