"The difference is Farley went first."

A Pair of Docks - Jennifer   Ellis

The first time they travelled, they ended up in Newellay (New L. A.) in 2036.  

 

The second time they travelled, they were unable to tell where and when they were, but definitely elsewhere and technology was different enough to be very noticeable.

 

the third time, they followed their dog through the stones, and they initially thought they hadn't travelled at all -- not until they returned home to find a very aged Farley greeting them at the door.

 

then they got out.  They got out fast.  

 

 

Future Farley and Now Farley didn't like each other.
