Drill Or Real?

This is happen when I together with my friend wanted to went down to KB and do something lah but on the half way just passed JP not so far away and we have to u turn back using the old road to Tutong town. Not so use what is it but I think is some kind of drill kali. Coz last week I remember someone said on one of the meeting started from 23th there is an oil spill drill some where on that time. So I think maybe that is the one lah and this drill is for 3 to 4 days like that also they said they going to have a drill on sea or beach lah.... So guys if you have caught on this road block please be patients lah and don't bising bising on making a u turn back!!!
