I'm going without my wife but with my two kids, Cauliflower (12 and 9 yrs old). I'll be staying between my mum's and my sister's (near Putney!) and family will be descending on mass. It will be barbecue central and plenty of in-house partying. I told my mum to remember to put alcohol free beer and tonic water on the shopping list!
Well done on Canada day btw!
