"Mac! I sent off the ones that we felt was the best candidates. I hope that a few of them will accept the terms. The Mother ready to go? And Gus? Is the bus running well?" Professor Gustav or just Doc, spoke as he walked into the large shop.

"Good. They might. Yes, yes and yes. Now we wait. Let's eat." came the gruff response from Mac as he came out of the bus.

A student laughed at the letter after opening it.

"I can't believe that the old Doc is still in business! Time travel is not at all possible......... My older brother went through a boring summer with that loony professor." 

The student then tossed the letter in the nearest trash can.
