There was water skiing last week. There was also swimming, boating, diving and other lake play, but through it all the air seemed cooler (it was) and the water seemed colder (IT WAS). The lake temperature is getting close to the tipping point that divides swimmers. Last we checked, the water borne were shades of pink. Soon they will be shades of blue. In addition to EM spectrum based changes, the auditory responses of those that dive into the lake will soon change from joyous to more screamy.
