Oshkosh, Wis.(WFRV)--People have been feeling the heat at EAA Airventure in Oshkosh.
A little shade, and some water was enough to keep some people cool.
While others, didn't fair so well.
As of noon, medical personnel took 4 people to the hospital and treated 25 people on the scene for heat exhaustion----and expected that number to rise as the day went on.
EAA had to create an extra cooling area as more people kept coming in.
EAA has two medical centers on the grounds staffed with nurses and doctors.
They say they are prepared for any medical emergency, though they are hoping today was the worst of it.
Local Five's Caroline Rowland has the story from Oshkosh.
