Even if I did figure out where my dad was living in 1978, I couldn’t just walk through the door and say, “Hi, Dad! It’s me, your unborn son!” 

Bones and I kept pedaling down the street in silence, and Bones stared at all the old cars as we rode past them. “Lump, there must be a car show going on somewhere around here,” he said. 

Bones loved old cars more than anybody I knew, but when he was going to realize there wasn’t a single Prius or Hyundai on the road! 

I didn’t have time to get into that now. Better to let Bones live in ignorant bliss for a little bit while I thought through this disaster. The most important question right now was, if we couldn’t go into the future because Bones didn’t exist, how did we get back to a time when neither one of us was born?

I tried to think about it, but it was like trying to think my way through an impossible riddle. It was way too mind boggling. 

Bones and I rode past a street lined with baby maple trees. “Wow!” Bones said, pointing at them as we zipped by. “I’m not sure, but I think the trees have shrunk, Lump. They’re not as big. Cool! And we only went back four hours. Maybe time travel affects your vision somehow.”
