Today is expected to be the hottest day of the year so far. Temperatures are expected to reach the low 90’s in much of the North Country, but there are ways to cool off. One of those options for city residents is to hit the free public pools that are offered. Both the pool at the Alex Duffy Fairgrounds and the pool near North Elementary will be open an additional hour this week from 11:30 am through 8 pm. The pools usually close at 7 pm. The extended hours will run through Sunday.
