I think for those staying in the west will feel like going to
Pasir Ris is really to far, so ulu.
The furthest I go in the east is Bedok & Tampines
I think 6, 12, 15, 403 & 518 guides are the ones which I
have to go personally to Pasir Ris just to have them.
The rest of the guides(5, 17, 21, 58, 88) I can go to Toa Payoh,
Bukit Merah, Bedok, St Micheal, Bishan to get them.
Not ulu larh, got white sands nearby, got MRT station etc. Haha,
when i need to go down to the western side of singapore to get
guides, i oso think it is very far. Around 1 hour travelling time
on the train.
