We went on exchanges in Missouri, and I realized that so far I have spent at least a day in three of the four states in my area. I spent a day in Oklahoma in the mission home. I spent a couple of weeks in Arkansas, obviously. Lastly, I spent two days in Missouri. Just need Kansas, then I could say I have been in all four states in my mission :D.
I was with one of the Zone Leaders, It was fun. We were able to find two (maybe three) potentials investigators in the area that day.
