Yes good point --- it's pretty easy and quick to make the changes. I'd still suggest rehearsing the moves ahead of time, because the event is so utterly phenomenal that you can temporarily lose your mind while being in the midst of it. If you're already an eclipse veteran then you'll probably be a bit more level headed, but even though the 2017 eclipse was my third, I was still massively overwhelmed. Maybe it's just me, but I find these events so paralyzing that I almost forget to breathe! I'm sure looking forward to next April, and I wish everyone clear skies wherever you may be.
