Yeah i normally skate in Bishan park. Never try Paris or
Punggol. But then in ECP, there is nice view and lot of babe and
hunk ard. Beside that, i found the route there to be smoother and
free of branches and stone, unlike bishan park. On top of that, the
route in longer in ECP.
All is good except that the crowd are rather pack during the
weekend and it take me 1hr just to get there.
