When you take the long way across, there are seven dips on a Texas trip. Name them.

Mojo111 --

From the Panhandle (Delhart? Dumas? Perryton?) south across the state
of Texas takes a horse through the Canadian, Red, Brazos, Colorado,
Guadalupe, Nueces -- and finally at the border near Brownsville, the
Rio Grande River.

The Google search strategy is a Google Image search using:
Texas + rivers

It yields a detailed image map from the University of Texas'
well-known map library showing all of the rivers:

Great question -- great game.  We'll find out who in the family is a real Texan!
