Travel to Ensenada via Tijuana and ABC bus?

Hello there, I have been going regularly to Tijuana via San Isidro & Otay Mesa to visit my wife and recently with my wife to visit her relatives scattered all over town, not just were the tourists/visitors go in Zona Centro and Zona Norte. I have recently been in Rosarito also in September-October 2009. I have even sent/paid for my wife to go from Tijuana to Cuidad Juarez using El Chihuahuense busline. The stories you hear are exaggerated in the newspapers, television and the internet to get your attention like a little child does to get some attention. It should be safe to walk from your hotel to downtown Ensenada in the daytime. Is the Micro the same as the Calafia in Tijuana? I even know how to use these to go to Fraccionamiento Santa Fe, Buenos Aires Sur, Anabelle, El Laurel, Refugio de la Loma, Zona Centro, Zona Norte and other colonias; plus they only cost 8 to 10 pesos. Have a nice summer vacation.
