Query: Use the hell out of this during our Peace Corps service!

My wife and I joined the Peace Corps and served 2 1/2 years in Belize Central America. During that time we would also travel all throughout Central America as well as Southern Mexico. We purchased this book as well as another and as far as my memory serves this one was a lifesaver on our trip to Oaxaca. The maps in this book always seem to be a little better than the others and we found ourselves using it quite a bit. Also, since Belize is English-speaking we never really mastered Spanish. The phrases in this book we found very helpful and actually assisted as many times.If you're heading to this area for an extended period of time, I feel this book would be very helpful.
