Hmmmm....if it's a 6.0 route, shouldn't this post be in the TR section?
I'm only going up on the roof if the wind is at least 50mph, with the need for ice ice & crampons.
And why does it have to be done during museum operating hours? I'm sure someone climbing up on the museum roof in the middle of the night, in dark clothes with a headlamp, wouldn't be suspicious.
And I'm not using Windex. Spitting on the glass cover should do just fine. It will help keep the glass from fogging up. (If it works on goggles, it should work on the webcam enclosure)
I'm sure Bulldog will be more than willing to volunteer for the month of Feb, if he is in the area hiking around Death Valley.
