Do I get an out-of-town free pass?

Technically, I’m covered — I used a little sea salt in my oatmeal this morning.  But I’m not optimistic about my foraging opportunities in Manhattan, where I’ll be for the next couple of days. 

Which brings me to an important question.  Am I excused from the challenge on days when I’m not at home? 

I’m bringing sea salt with me to New York, primarily to show my friends what I’ve been up to, but also as Plan B in case I decide that out-of-town days do count, and I have to eat something self-procured.
