Hello,
concerning your comment "if you don't get the light, you don't have a problem" when entering sonoita...... Not true for me the last time I re-entered Mexico. the guy at the Lukeville gas station had mentioned the new sign saying that people cannot bring in food or dog food to Mexico and i thought he was kidding. I crossed with 4 ice chests full of the special kind of food that I eat. I got the green light, breathed a sigh of relief silently and then slowly proceeded forward but had a guard flash a flashlight into my rearview mirror and so I figured this meant I had to stop. (it was at night so I saw the light, not sure how well that would have worked during the day) Which i did and he proceeded to ask me to open up the back of my class B motorhome (which is basically a large van with a tall ceiling). He just poked around a little and I did not mention the 4 ice chests and then he let me go. I am working on my special situation of eating certain food due to a health condition since Mexico does not have what will work for me nutritionally. i own a home in Penasco and tend to go there frequently.
