I LOVE your traditions doodlebug!!
For us, we do the Christmas tree night like doodlebug. That's tonight at my mum's as our tree is already up
We do the drive around town looking at the Christmas lights. One of the radio stations put it on, there's a north cavalcade and a south one. We live on the south of Cairns, so we do the south one.
Christmas day we do a Christmas lunch. This year DH and I are putting it on. Still deciding what we're doing with it.
Boxing day we always do a bbq lunch with friends and cricket. Gotta have cricket on Boxing Day!
