MTA: Metropolitan Transit Authority is the local public transportation system for Los Angeles County. What can I say I depend on this bus service. It has it's ups and downs. Some of the bus drivers are just crazy. I have met some really nice drivers also. My biggest problem with MTA is that they are continually change the bus lines for the worst.. For instance a bus that used to go 10 miles each way now will only go 4 miles each way. It makes it really difficult to get around in their bus system without have to transfer to a local bus line within the city I am traveling to. Overall I have to deal with the bus system until I get a car.
