Eric,
I will get it back on the subject of batteries.
Did I tell you that my 2017 Zero DS 6.5 battery crapped out? That was great news, as it now has a 7.2 KWH battery in it (under warranty!) and what a nice big difference that made in range. In fact, I would not hesitate to ride it from Reno to Auburn, as I have no doubt it will easily make it to Truckee, and from there, I only have to get to Cisco Grove--all down hill from there. And I could also do Hwy 20 since they now have several J-1772's in NV City as well as in Grass Valley.
Lately, I have been mostly taking Hwy 20 between here in Auburn and Cisco Grove and then as many side roads as possible to Reno. But Donner Pass Road is closed for now, but from the west, I can still get to here (road is closed just a few yards/meters to the east of this very spot):
BTW, this photo was taken the same day you passed me on I-80 when you waved at me!
