I camped there most of the week. We were not in a crowded area.
What I noticed in the early mornings was there was no wind.
The generator exhaust would just float around the RV creating a cloud surrounding the RV.
You could observe it on RVs in the distance.
If we opened a window for ventilation, the exhaust would just come right in the window.
Going outside might not help as the cloud was out there.
I was very aware of it and used different Fan strategies all week to keep the fumes out.
We saw an ambulance at a RV near Winners Walk II. I wonder if that was the one?
