Man, I feel this so hard! I did the exact same thing last fall in Colorado. My lens fogged up so bad it was like looking through a shower door. I learned the hard way that you gotta leave everything in the bag when you come inside a warm tent. Now I just sleep with my camera in the foot of my sleeping bag, which is kinda weird but it works. That slow warm up in the car trick is totally the way to go.

Heard a podcast where someone said their 100th bowl showed them the same thing.

Why not glue the furniture down?
