Read. It seems silly, but if you use common sense it jives.
1. Big outbreaks in summer in hot climates. Not so much in cooler climates.
2. Every study on human coronaviruses show they prefer cool dry air to spread.
3. Texas contact tracing has shown that the vast majority of cases are tracked to indoor venues specifically bars and restaurants.

All this is true. The virus is spread almost exclusively indoors. Specifically, as you said, in crowded bars, family gatherings, etc.
People who say “well so much for the heat killing the virus” aren’t seeing the forest through the trees. The hot weather may not obliterated the virus, but it does not spread very well outside according to every contact trace data available.
Our issue right now is people are still having big indoor gatherings. Adults (NOT children) are bringing it to parties/events and spreading it amongst themselves.
This is why sending kids back to school is a no brainer yes. And college kids playing football in limited capacity outdoor venues would not be a major negative contributor to the spread- if common sense can ever prevail. I’d still think fans should wear masks entering the stadium and whenever they go to the concourse though.
