High temperature of what?

(From left) Police Chief Don Strom; Don Moore, police officer; and Wendy Oloteo, information and evidence assistant, along with two other members of the WUSTL police force (Raymond Schmidt, police officer; Mark Glenn, sergeant) jump into the frigid waters of Lake Saint Louis Feb. 4 during the Law Enforcement Torch Run Polar Bear Plunge to raise money for the Special Olympics of Missouri. Humorously dubbing themselves “pigs in a blanke” they wore pig masks and huddled under blankets during the event —the officers and more than 150 others braved temperatures in the upper 20s to raise more than $44,000.
