When touring, I use bolt on skewers instead of quick release to reduce chance of wheel theft. Not the skewers that have a special key that I would lose, ones that any 5mm allen wrench will work on. I store a spare 5mm allen wrench with my spare tube for obvious reasons.
That said, when not on a tour, typically use quick release in back. But usually use bolt on skewers in front on bikes with dynohub wheels when not touring.
