It's all about soccer in the Geo Quiz Thursday.
Mexico's top two professional teams are ready for their showdown.
They play each other Thursday and Sunday, in a two-game series, to decide which team will be the national champion.
One of the teams is from Toluca in central Mexico — the other is from the border city we want you to name.
The answer is the Mexican border city of Tijuana which is in the grip of Xolos fever right now.
Xolos are a canine breed that we Americans know as Mexican hairless dogs. But Xolos is also the nickname of Tijuana's professional soccer team which is battling for the crown of Mexican champion this week.
The World's William Troop tells anchor Lisa Mullins about the team, and its passionate fans.
