MapForums

I am relatively new to Mappoint. I am in medical sales, and create my own maps to set up routes around Los Angeles. Although I am fairly thorough in my own research, someone told me that it is possible to download sets of data online. I can't seem to find anything like this. I am not looking for anthing too complicated, simply plotted hospitals and medical offices in the Los Angeles area. Please point me in the right direction if you know anything about this.

thanks,
