Well, at least it gives them the hope that they are closer to the surface of the earth’s crust…  Me, I’d be freaking right about now.  I am just looking at this… remember heights?, enclosed spaces?  Some adventurer I’d make…

Sorely disappointed that Mark didn’t leave his shirt behind, or at least take it off and tie it around his waste…  you’d think he’d use any excuse for that…  but oh well, probably didn’t want to make Gabe feel self-conscious…  especially as he brings up rear.

Funny how every now and then, like in the third panel, it just doesn’t look like Mark.  We are familiar with his son Rusty, the Shape-shifter, but not Mark… right??
