You obviously don’t spend time outdoors
Spending time out in the hot sun will always be better than a cool summer .. Whether you’re at the beach or out in your backyard, nothing beats a summer’s day in the sun. I’d sacrifice a bit of cash for the AC to have warm summers any day.
I hear ya sista!!! I can't
I hear ya sista!!! I can't stand the hot, humid weather.

Every weather forecast is a "crap shoot". They called for a warmer than usual spring/ March and April. So far the weather has trended colder than the historical average.....Meteorologists are like fortune tellers...Very inaccurate, especially over the long haul. The Farmer's Almanac is even worse.
lol. I feel you. I want it to
lol. I feel you. I want it to be warmer too. I can't stand the depressing cold weather especially since it is already April. Not all weather forecast predictions are accurate so you can't blame the people who own this website. Hold on, it should be getting warmer soon. The cold can't stay with us forever. ;)
