getting back..

yesterday tried to come back my uni by solely depending on the GPS that i just got... the navigation was quite good only... but it sure does lead me to the fastest road.. as everytime i reach traffic lights it will turn green... dunno its such coincidence or it can really calculate it... the bad thing of depending the GPS is it will lead u to use expensive ways... wat do i mean?? it means that since malaysia have so many tolls it will not direct u away from it... so at last i needed to pay more tolls.. so next time if i know the road i will never ever depend on my GPS... unless i am really rich....
