The battery for my Zoom video camera was dead and I put it for charge; I'll also charge up the extra battery I got. I may ask someone to also record on their iPhone in case the video gets botched, since I barely know how to use the device. I find that the Apple phones generally have better sound than Android.
My hands and wrists are still tired and maybe this is a sign that I need to do minimal practice before I leave. Maybe I'll just run through everything once today with the recorder and then do a few touch up things tomorrow.
