Time Travel in Portland

"Dad!" Gabriel shouted. "Look another time tunnel! We're going back to the future!"
I sighed. Gabriel had been declaring a time tunnel at every bridge and signpost. The freeway drive to Hannah's hospital was about a half-hour from our house. That's a lot of time travel.
"Gabriel, can we go back in the past?" I suggested. A break in the routine seemed in order.
"Sure!"
"Okay," I pantomimed, "Now I have a horse, and I'm driving a carriage. Nice horsey!" I reached out one hand to pet the mane, keeping my other hand on the wheel. Gabriel made clip-clop noises.
We tipped our hats to the imaginary ladies. "Good morning, ma'am. Sir."
"Look - another time tunnel, Dad!" Suddenly, we were back in the future. Our horses transformed into robot dogs and our carriage into rocket cars. Just as suddenly, we flipped back to horses. The interchanges, signs, and bridges were coming fast and furious as we neared the hosptial.
Finally, we made it to the hospital parking lot. The parking lot proved to be yet another time tunnel. However, as we disembarked from our ship and walked toward the hosptial doors, Gabriel noted, "Dad, the hospital is the real world."
"Yes," I agreed with him. "It is."
