Is there any guide or map of the Public Car Routes, The Hand Signals that the drivers use, or GuaGua routes available? I can pretty much get to where I'm going but sometimes I think maybe there's a better route, more direct. And how about a bus from SD to the beaches at Juan Dolio/Guaycanes. Which Agency regulates these cars/vans/buses? Maybe they have some info, do they have a website? I know, hehehe, but I had to ask.
