Well, if everyone fans out we'll find him eventually, I hope. If we don't find any trace in the next hour we'd better head back though before we get lost ourselves.

[Sun's useful for navigating, but a big wide desert still leaves him on edge with its unfamiliarity. Walk too far and sure, they could find their way back north or wherever, but if they've drifted farther east or west than expected they could miss the town entirely trying to get back to it.]
