Hey JT, serious question here. Why would your family leave Boulder if there were no electricity and go to the higher altitude of the mountains? It is colder, windier, snowier up there. How much was the town functioning when your family left? When you returned, the residents had obviously kept some technology alive, or the time machine would not have been ready so quickly. Any hints on how to be in the group that somehow preserves and protects that type of technology?
