Yes, I work remote for my old job in Silicon Valley. I really haven't tried to find a new employer, and I'm many years away from retirement, so I don't know what will happen when it's time to change jobs.
If so I would suggest start learning new technologies, start adding simple projects to you github and writing on linedin.
Seems like too much but just start one thing at a time. This way you will dramatically increase your changes of finding another remote when when necessary.
But in the end of the day you also need a plan B, which is money saved and some idea of where to go in case you need to move back to the city to find a regular job.
