I'd been relying on Google Earth, and found this kind soul's .kmz file, in which he/she included all the major roads, shops, restaurants, etc.

PM me your email if you want me to send the file to you... =)

just trying to "pass the good deed on"... =)

(for those unfamiliar with google earth, u must first d/l google earth to open the file, and then you can customize your views, 3D, plan view, side view, etc.)
