Here is a story about the exact type of portable toilet used for the Stornoway garden party.
This is apparently what I miss by not going to more garden parties.
It presently is garden party season in Ottawa—the Speaker’s reception at Kingsmere was last evening, the leader of the opposition hosts at Stornoway tonight, there’s probably something at 24 Sussex at some point. The press gallery is in these cases invited to mix with the political class in smart casual wear and, at least in the case of 24 Sussex, an inflatable castle is provided for children.
