I ran my furnaces (front and back) all night to keep warm because temps dipped to 24 by early morning. Then when I woke up, I discovered my house battery was almost dead and my generator would not start--did not even turn over, just clicked. That was it.
I had been seriously thinking of leaving early because of the cold and damp and grey skies, but this did it. In addition, I had had to go all over the park yesterday to find internet service. I did not mind paying $5.95 but not happy that the visitor center guy had sent me first to free internet at Curry village. (I had originally been told I could get a signal in the visitor center.) Took the shuttle, walked around trying to find the right building, only to discover that only a certain number of people could be on at once and it was full, plus being really weak signal. So on to the Yosemite Lodge, where I paid and then enjoyed a drink and cookie in the café. By the time I got back to RV, I was beat. I did visit the museum and Indian displays, but skipped the Ansel Adams place because I had been there about 15 years ago and was cold and tired.
I had hoped to take a tour to Wawona and Glacier Point, but there were road closures and no tours were running, other than the valley tour, which was booked. The snow was pretty and it was an adventure, but I do not recommend going there this late in the season. I'd have been fine if I had gone three weeks ago as originally planned or when Beth was there.
SO I am back at Hensley Lake for a few days before returning to Napa for my procedure. It is sunny and relatively warm here, and I have power for satellite TV and my internet is working.
By the way, there is Verizon and AT&T cell voice service in Yosemite via roaming, but no data whatsoever. At 3:00 am I was able to use my phone to access a couple of things online but it was very iffy.
