Carolyn's mission president for the Central mission has a blog also.  I was just reading it and HAD to share this story from it!  It is written by his wife:
Every day we see miracles in the mission field. Every missionary experiences these miracles during their service. What is really a great blessing for President is that when he reads the weekly letters of the missionaries he hears about these miracles. Some are very sacred that we could never fully explain adequately and some are just everyday occurances in the lives of obedient missionaries. One of the focuses we have had is "Abrir su boca", open your mouth. We have set some very high goals in our mission for contacting every single day. Some missionaries are great and attack the goal with complete obedience, faith and diligence. While others are not so believing....'it is to hard, what purpose does it serve, etc.... Of course as the missionaries obey other areas that they have goals in begin to happen and the faith begins to grow. Many miracles that happen are in the lives of members and especially in the lives of the investigators. I want to share one such story about the miracles of missionaries opening their mouths and doing what the Lord has asked. Being robbed here is a very common thing. The way of travel for all the missionaries is by 'chicken buses'. These buses are very very crowded and many times robbers come onto the bus and rob everyone including the driver. There is nothing they can do but give the men what they want because they are always armed and they travel in groups. Sometimes the miracles from being obedient are never seen by the missionary but they are always noticed by someone.

This experience was told to us by Elder Euteneier:  "We have an investigator that was going on a bus to Escuintla one day. Four gang armed members entered the bus and everyone on the bus knew them and knew that they were going to assault the bus. Two of them stayed up front and sat down, two others went to the back of the bus. Everyone on the bus, including the investigators were all nervous and anxious when eight of our missionaries entered the bus. They began to contact the bus. Four Elders took the front of the bus and four Elders took the back of the bus. Unbeknowest to the missionaries they contacted all four of the gang members at the same time and gave them pamphlets. At the next stop, all four of the gang members got off the bus without a single threat. Our investigator told me that we are definitely sent by God to guide and protect the people here. So not only does contacting buses rid us of fear, help us find chosen people and spread the good word but it protects agains Satan's agents as well."
