I lived in Mexico about half of my life, speak Spanish fluently, have family there, and would love to just jump on the plane, fly 4-6 hours, spend one night and come home.
Instead, I drop about $1.5k or more to fly commercially every time my wife and I want to go visit.
I know plenty of people who have successfully flown there and back, had lots of fun, no problems, etc. I also know this is a country where the law is not what's written in the books, but what the guy with the gun and the uniform says it is. On top of that, there is a full-blown drug war going on, and the police/army's attitude towards general aviation seems to be that you must be running drugs unless you convince them otherwise. It only takes p**sing off the wrong guy one time for things to get bad in a hurry.
If I had been flying 10 years ago, *maybe* I would consider it. Now...no way I'd risk losing an RV I spent years building to some thug with a badge who likes my airplane, my money, or both.
Just my own perspective on things, which I admit is certainly biased

-- I bet you can probably make it Veracruz, fill up and leave with no issues
