The mean thing is I waited a full year before I moved them in there. Checked for leaks, checked after really heavy rain, and have always made sure to keep the drain in front of the office clear.

I cleared the drain shortly before we headed to Melb, but the winds and rain blew down enough crap in that short space of time that it blocked enough for the water to back up into the office.

3-4 more weeks, that stuff wouldn't have been in there.

On the bright side, I'm pretty sure none of the stock stored down there has been hit.
