And to this point, it hasn't mattered what I do, if I plant any kind of squash, it gets it. We are hot & humid here. Our normal humidity levels during the summers range in the 70%s & higher.
But I planted some the other day in one of the raised beds...so we shall see what happens there!

Raised beds are exposed to the same air as the in-ground beds so I would not expect to see any difference. I was wondering if floating row covers might help to keep the spores off of the plants so I Googled it and it turns out that they DO work.
Of course squash need pollinators so you have to remove the covers periodically if you want pollination or plant a parthenocarpic variety like Perfect Pick zucchini that does not require insects for pollination so you wouldn't need to remove the cover.
Karen, I have 5 seeds of Perfect Pick left from 2013 that you are welcome to have if you want to try the row covers. Just PM me your address if you want them.
If you don't want to try row covers, I would spray with the baking soda solution periodically between rains.
Here are a couple of articles about using row covers to prevent PM

While many people think that Powdery Mildew needs hot and humid weather to grow that is not the case. PM does most bestest in moderate temperatures and moderate humidity.
Floating Row Covers, if the mesh is fine enough, can keep the spores that cause PM from the plant leaves.
