Willis/Chris - Many thanks for the information. That's a help.
Steel - Crew aren't allowed to wear shoes during the trip.
I've run out of NA Old Milwaukee - I'll try to find a replacement, perhaps Busch NA:
Fully brewed with finest natural ingredients, including a blend
of premium American hops, fine barley malt, cereal grains,
and pure water. After full fermentation and maturation, the
alcohol is gently removed to preserve the quality of the beer.
I'm not sure why it's important to "gently" remove the alcohol or what happens to it.
I'm also thinking of changing the breakfast menu to either pancakes or flapjacks, with blueberry syrup and coffee. Or maybe beef jerky and potato chips washed down with homemade Yoo-hoo. Can't decide.
