Pleasanton is hosting five student delegates from its Mexican sister city, Tulancingo, through next weekend.
The youngsters participating in the Pleasanton-Tulancingo Sister City Association youth exchange program are Jose Escorcia, Rodrigo Valdespino, Marian Macedo, Maria Teresa Rosas and Andrea Martinez.
The exchange program is a family affair for almost all of them.
Escorcia's grandfather, former Tulancingo mayor Eric Saucedo, signed the first charter for the sister cities in 1983, along with former Pleasanton mayor Bob Butler. And Escorcia's mother, Zelena Rodriguez, later became one of the first students to take part in the exchange program between the two cities.
Valdespino's father was part of the first Tulancingo delegation to visit Pleasanton. Macedo's brother was an exchange student here in 2011, and Rosas' brother participated three years ago.
The teens, who are staying with local host families, arrived in Pleasanton on June 19 and are staying until July 10.
Their trip itinerary includes tours of Pleasanton City Hall and the library's Tulancingo Room, sightseeing in San Francisco, attending an Oakland Athletics baseball game, visiting the Alameda County Fair and Santa Cruz, taking part in local Fourth of July celebrations and a farewell picnic at the end.
The sister city association is set to send three student ambassadors to Tulancingo later this summer: Amador Valley High student Kata Zengel, Amador Valley graduate Sara Keene and Castro Valley High grad Maia Barthman.
