Waterslides that should probably require helmets but everyone rides face first anyway. Collosal beers rimmed with chile and chamoy. Tambora bands, corn on the cob on the grill, Tecate eagle fake tattoos, a Tarzan rope. Everyone says Disneyland is the happiest place on earth. But they’re wrong. Welcome to El Vergel, Baja California’s largest waterpark and home to the borderland's largest and arguably most gnarly waterslide, the Slip N Fly.

Tickets include roundtrip border transportation, park admission, en-route libations and complimentary artillery for the en-route water gun fight.

The group meets at the San Ysidro Transit Center at 10 a.m., with an estimated return to the border at 6 p.m.
