What is it with Argentinian's and campsites!

So it's hot and we're in the nicest park (as opposed to San Rafael's) in Argentina. It took a while to find the camping ground in the park and as usual we have a police escort to get there. The camping ground is heaving. It's a Saturday and there are people everywhere. We squeeze into one site and pitch our tent. In a camping ground of over possibly 100 sites, there is only one other tent pitched. We learn that these guys consider camping grounds to be a place where you go for a family BBQ, not neccesarily to pitch a tent and stay the night. That doesn't mean that they all pack up and leave us in the piece and quiet to sleep. The luch crowd dissipate and are replaced by the younger evening crowd. Then a wedding party turns up at about 11:30pm beeping their horns with at least 10 cars in tow (They obvioulsy got the last time slot for the church booking). These guys do know how to party though, they we're still going at 6am. Thank god for ear plugs!
Three nights in Mendoza Municipal Camping ground was enough, that plus the mechanic that we were hoping would work on Mike's BMW can't help us. So after a swim, the excercise nearly killing us) we head off to Chile.
