When I was a small child, Texas summers were 80s-90s.
When I was in college, Texas summers were 90s-100s.
When I was in my thirties, Texas summers were 100s-110s.
You see where I'm going with this?
This happened in my life time and I sure as hell paid attention to it.
One reason I chose our current apartment it it's newer and thus better insulated and it's as shielded from the sun as possible.
Because I KNOW it's going to get hot.
