I vacuumed and washed my floors ( leaving the house redolent of Method Wood for Good with almond oil ) , dusted and changed my sheets , while other laundry rumbled in the basement . It was while I was in the final stages of vacuuming my bedroom that lidocafe phoned and invited me to go the see a couple of the historic places open to the public this weekend . Remember I mentioned going to a couple on Canada Day ? Well , today is " BC Day " and it 's our 150th birthday this year , so some of the same places plus one or two more are open this weekend as well .
