Welcome from north of you in the Mid-Willamette Valley of Oregon.

1) Personally, no.

2) Maybe it's the subliminal marketing from the blue light.

3) I prefer my cigars to be in the low to mid 60s % RH when I smoke them. This is where I keep my desktop humidors where I pull cigars from to smoke.

Any higher and they can feel plugged, not burn as well, and taste acidic. That said, my coolidor seems to want to stay at 75% RH, but I don't pull cigars here to smoke, rather to stock the desktop humidors.

There's a general range, but ultimately you decide what you prefer. Also, some cigars tend to do better at different RHs.
