In the midst of a monstrous fire storm that might not be easily done. The accounts of that event are mind boggling. The Tubbs fire generated winds that overturned cars, left them belly up.
I'm loving my manual door right now, never worked better. I put new springs on it back around 2001 or so but I didn't do it as neatly, as well as I did last week. However, having that door working on only one of the two springs for a couple of weeks or more took a toll on me. I raised the lowered the door with brute force several times a day and wedged a ~7 foot 2x4 under it to hold it open. I didn't really feel the strain until I'd gotten it all back together and working nicely with two springs. I felt a twinge in my back and that degraded into a real problem several days ago. I'm 85% over it now, I was getting close to alright in the gym yesterday. Figure I'll be OK in a few days.
