Unfortunately no; never had the opportunity. However I did meet several argentinos on vaca in Chile (made several consulting trips to Santiago); several approached me on the street asking for directions...guess I looked trustworthy
Reminds me of a common joke. Un shileno y an argentino estan chismeando; en algun punto el argentino se pone molestado y le dice al chileno: sabes, hombre, del comico al ridiculo solo hay un paso. Responde el shileno: claro, y se llama Puyehue.
