Chapala Jalisco Mexico. Perfect climate, highs in the summer are in the low 80's, with lows in the mid 60's, winter highs mid 70's, with lows around 60 degrees. 50 mile long lake full of bass, and on a busy day there may be 4 or 5 bass anglers on the water.
There is a large US and Canadian retirement community. There are many hiking trails, bike trails, coffee shops, gyms, and yoga classes for my wife, and big bass for me.
Drug violence in Mexico is over exaggerated. Yes drug gangs do shoot each other, just like they do in the states. The police and politicians are often in the cartels pockets, but that has nothing to do with the safety of retired people minding their own business. There are zero road rage shootings, and I haven't heard of any school kids getting shot in school. Most of the time when you hear about an American getting killed in Mexico by drug gangs, the press didn't bother to find out the whole story. A Canadian was murdered in PV a few years ago. It was all over the news in Canada. Head line read Canadian killed in dangerous Mexico. I new the man and was shocked. He was shot in the back of the head while getting a coffee at Starbucks. It ended up he was the head of a gang in BC. The hit was done by a Canadian mobster, and he had been hiding out in Mexico for years after they tried to blow him up in Vancouver. He wasn't even shot by a Mexican. Another time some college girls from Sweden were murdered in Acapulco. It was a terrible crime, and caused many tourists to quite going there. Again the news papers did not convey the whole story. The girls spent a week hanging out with some drug dealers snorting coke, and smoking meth. in the drug dealers condo. After a week, they got bored with the drug dealers, and decided to move in with some tourist men they met on the beach. When they moved out of the drug dealers condo, they decided to take some drugs and booze with them. When the dealers came back to their condo and saw the girls had moved out with their booze and drugs, they did exactly what a drug dealer in the states might do. Of course these women did not deserve to get murdered, and I assume the police made zero effort to apprehend the murderers, but if they had not spent a week taking drugs with obvious cartel members, they would have had a nice tropical vacation. Can you get killed by a stray bullet in Mexico? Yes, but the odds are about the same as getting shot in the US. If you want to take drugs, and party all night long, it is easy to find trouble. The attitude, what happens in Mexico, stays in Mexico can get you in trouble. Catching giant bass that have never seen a spinnerbait will only get you sore arms, and a permanent smile.
If you want to live somewhere that is inexpensive, has a large US retirement community, a fantastic climate, very little fishing pressure, is safe, and has giant bass, than Chapala is the place.
