i stay at woodlands, i going changi air base at loyang ave , i
did some studying and i find 858 takes me out fastest by SLE TPE
then PIE just like taxi route, but 858 ends up somewhere off from
changi air base so im thinking if theres any bus along tpe i can
switch on after 858 that can bring me to the airbase asap
say so next time 
take 161 to punggol road, cross and take either 89 or 109. lagi
express
