Ha ha, GWH! I love the title!!!
I DO hope Gastón has fun, as well as being paid lots of $$$. And it's great to get some clay practice before the ATPBA. Viña is a nice place - I was there last month when I travelled to Mendoza in Argentina via Chile (a fantastic trip, crossing the Andes near the Aconcagua), but the Chileans with their Chi-chi-chi-Le-le-le drive me wild.
I guess we're a bit more sophisticated over here, but honestly they're insufferable, and I've never forgiven them for what they did to poor Zabaleta's dad during a Davis Cup match, when he was hit by a flying chair!
Anyway, they love Gastón, and he was a great success when he played that exhibition match with Massú, a "Gran Gaudio" included!
