Perth, Australia hosted the CHOGM in 2011 and that city faced a virtual lock down, with even the police force of New Zealand joining in the security arrangements. An extra public holiday was declared (by shifting the Queen's birthday holiday back by a couple of weeks) to reduce public inconvenience.
If these were the arrangements in Australia, a place which is not security conscious in the least, the mind boggles at the thought of what arrangements will be made for Colombo.
So far, there is some speculation of a single public holiday, but nothing else. I have a feeling a good part of the roads in the centre will be closed with probably two official public holidays, but for all intents the entire week is likely to be a non-working one.
Not that I mind, I need a holiday and as I have almost no leave, any additional public holidays are only too welcome, especially since the poya in November falls on a Saturday. I just wish they would announce the holidays in advance, so that one can plan a getaway.
