They tray system in a place like Arizona and Vegas (which is cool to see) thrive because of year round sunlight as well.
Cincinnati winters ?? Yeah, not quite the same. Everything seems to die this time of the year, so that presents its own challenge.
What that looks like in places like New York, Minnesota or any other northern (winter) cities can vary as well. But hey, if there truly is that big of a difference, then I’m all for the change.
However, I think in some instances they would simply be trading one problem for another. Think the old Cincinnati and Pittsburgh fields. Horrible.
