A gang located in Caldwell,Idaho, with it's original roots from VLT (Varrio Loco Trece) a gang from Texas. ESL's varrio is located on the east side of Caldwell, and their main rivals are the West Side Loma Locos also from Caldwell. They are also rivals with North Side Nampa. ESL claims the number 13 or trece. (ie-ESL13). Many of ESL's veteranos are currently incarcerated in state prisons, some as a result of putting in work against the Lomas.
