what kind de. I suggest you to buy the Public Transport Map by
Mighty Minds, as that book contains bus informaion. Available at
major bookstores.
Or you can buy the "Singapore Public Transport Guide 2009" (Cost
$6.00)
by SCIP enterprise pte ltd. Available at major bookstores.
of these two, i feel the singapore public transport guide
is better. it at least shows the buses that go there right on the
map itself, unlike mighty minds' which shows it on the right hand
side and can get a bit confusing. the mighty minds one also tears
VERY easily :S
