We crossed over into Nuevo Progresso when my youngest daughter was <2 years old. My sister in law lived in the McAllen/Mission area and we'd visit every year. It was always a good time and I snicker at the guys who are doom and gloom when it comes to Mexico. Yeah it's a 3rd world country but it's not as bad as some areas here in the states.
Oh yea they know how to have a good time for sure!!
