What is the hardest part? Being away from family?
This is the obvious one, even though technically I'm home more now than when I worked at B&H.
The other hardest thing is definitely the food - planning, preparing, dealing with missed baggage, logistics of cooling/freezing/heating while switching between multiple locations, organizing and serving, making sure there's always something for everyone, and a million other things. When we come back from a full day, everyone gets to relax but no matter how tired I am I have to deal with dinner now... Food is a 24/7 chore. (Again, not complaining. That's what I'm here to do...)
And of course unforseen circumstances. Sometimes they're minor and sometimes they can turn an entire trip upside down lol.
