I just had a recurrence of my laptop failing to sleep problem. I did some Googling and found this suggestion, which is worth knowing if you ever have a similar problem with Windows 10...
Type 'cmd' into the start/search box. Right click on that and run it as an administrator. Type 'powercfg /requests'. That will show you what is messing with your machine's attempts to power-down.
In my case I discovered that Windows Media Player was doing it. I only use that once or twice a year, but one of those times was a couple of days ago which is when the sleep problem kicked off again. I went into MP options and turned off everything that looked like it might try to keep the computer awake. I rebooted the laptop, then closed the lid. I opened it again and it came back to life. I've put it to sleep numerous times since then and it always woke up again when I opened the lid so it looks like the problem is fixed.
Just got back from my measly 18.5 miles and it was divine....blue sky, 20C a light westerly breeze and now it is lunchtime. Doesn't measure up to your gorgeous scenery...
I just Googled Casper, Wy and there seems to be some pretty impressive scenery out there too!
The thing about Britain is that it is a very compact country. We do have some lovely countryside but it is on a smaller scale than that of many countries including the USA. If you go to the Highlands of Scotland you can get to some majestic mountains, but even our highest (Ben Nevis) is only 1,345 m (4,413 ft) high.
I just wondered how remote you can get on the British mainland. Apparently, the furthest you can get from a public road is only about 10-11 km (6-7 miles). Admittedly, the terrain to get there might be very tough to cross!
