I traveled extensively throughout Mexico during my w*rking days. During 2010-11, I seemed to wake up every morning and hear about a violent cartel event very close to me (Monterrey area). It was unnerving. The extent of the torture was unbelievably gruesome (ie, stitching someone's face to a soccer ball and tossing out onto a neighborhood field during a game). However, it was all cartel on cartel war (but often against police, media, etc) for control of the Monterrey turf. I relished the culture, hospitality, and work ethic of the people of Latin America.
When we were planning for retirement, the Lake Chappalla area was our "plan B" of several expat locations. Medical care there and in Guadalajara were part of that equation. But as we enter exit turn 2 (Nascar lingo) of our third year of retirement, plan A is working out fine.
