Alan's office takes no chances

Alan took me to look at the water defences at his office.

 Coming around the corner from Jim Thompson's cafe.

 You can see that the buildings are pretty high up above ground level anyway.

 How many sandbags is a lot?

 This many?

 Or this many?

Look how high they are above head height!

I suspect this building will be the safest place in BKK should an epic flood appear.
