The casinos listed in Wizard's post are all Boyd properties.
Thanks for posting the pics, MDawg. Here in the Gulf South things are much more relaxed. All casinos are required to have every other slot machine turned off. A couple places are using the plexiglass but they're in the minority. Temperature checks are mandatory in Louisiana but optional in Mississippi... a couple places do them anyway, most don't.
Masks optional everywhere (at least for customers... mandatory for employees) and I would say mask usage amongst patrons ranges from 50-60% in the two New Orleans area casinos to under 30% in the Mississippi coast casinos.
Not much social distancing is taking place, and there's really no way to enforce it anyhow.
