Travel in Michoacan Question

Thank you for your replies and positive responses. The four of us drove from PV to Comala, Zamora, Morelia, Z and back to PV in the past and my wife and I have driven from Z up to Taxco, Cuernevaca and back as well as trips out from PV so yes I love the region and diversity and have never been in any kind of hassle. That said as Rob points out there are interuptions periodically in the bus routes due to protests so I guess if we decide to go inland and the bus is not going there we head up the coast.
