My paternal grandfather served in the RCAF in Yukon and Alaska during the Second World War. The air force bases were all dry, which didn't sit well with my grandad who liked his tipple.
To remedy this, my grandmother apparently used to regularly send him hollowed-out loaves of bread with bottles of rye stuffed inside.
Just found this out this morning during a phone call with my mother. I thought it was funny, so I wanted to share.
