I hadn't either, but yeah, a totally different feeling thinking, at least, that you'll be out for quite a while. I had that situation last year starting the PCT pre-Covid, planned on 2 months, then wham the pandemic blossomed and it wound up being only a week. During that single week, before I knew how bad the pandemic situation was, I was already in the wonderful long-distance mental state, or nearly there.
But if it's only a planned 2-weeks or so, I don't get into that glorious long-distance hike mind set. 3 or 4 weeks planned, maybe.
I like this for a definition of a LASH. If you get into the "zone", it's a LASH.
