Two BEC Events in early March 2023

In March 2023 I am covering two BEC events happening almost simultaneously: one in Houston, TX and second one in Las Vegas, NV.
The former one is 2023 IIBEC International Convention and Trade Show, the later one is 2023 BEC Conference.
In spite of "BEC" in both their names, these venues and their organizations couldn't be more different, and these differences I found interesting enough, that we would cover them in the upcoming movie about building enclosures.
