sorry for not posting sooner; i've seen people shooting (archery) here in the mornings.

i went by the site today but no one was there.
btw, the temporary wooden motorcycle/pedestrian bridges between hypermart and the archery site are closed due to construction of a new bridge. well, ya can't be sure it's for a new bridge but the wooden bridges are gone and there was an excavator in the river.
