I actually live at the edge of Garin, not far off the Panamericana Pilar branch. I'm actually between the Tortugitas exit and the Del Viso exit. A neighborhood called La Legua.
I didn't realize that anyone from the forum lived out here!
BTW - we looked at schools in the Del Viso area and saw some nice ones, just a little too far from us (Tortuguitas is a little closer with easier access) and we couldn't find a school bus company that would come to our neighborhood to pick up.
I've thought about looking for a house outside of a closed neighborhood, close to where I am now, and in Tortuguitas and Del Viso as well.
The biggest issue for me is safety. The truth is, I feel safe where I am, even in the neighborhood outside of my closed meighborhood. The people seem nice, the properties are well-cared for (for Argentina) and it feels comfortable. But we have a woman that comes to our house on occasion to help with clean ups after parties and such who lives nearby and has told me emphatically that I should never think about living outside of a closed neighborhood if I can at all avoid it. She lives closer to Garin, about 1/2 kilometer from me, and it could be where SHE herself lives, that is the big problem. But I've talked to her about nearby and she says if she had any way to live in a closed neighborhood she would do it all the time because of the problems they have all the time with gangs of kids roaming around and stealing crap, etc.
In fact, we have about 3-4 break-ins into the neighborhood every month. So far they have not gotten away with anything - our guards are very attentive and they have foiled every attempt since I've been here. But the amount of attempts make me wonder what it would be like if I lived outside, in a regular house, even with walls around the lot. I have a lot of electronic equipment (part of my job) that would kill me to replace, not to mention my data and such.
