I removed the battery from the Zumo and re-installed it and it fired up. Track uploaded.

I logged 207.1 miles by the time I got home.

My spare Zumo 550 that I used on this ride seems to have failed. I turned it off and pulled it from the cradle and now it won't turn on.

This ride is over.

Yermo is home safe.

Just managed to avoid that impressive thinderhead ... I am now safe and dry at McGinty’s.
