I ended up deciding I wanted to bring both processors for the trip, so I redid the packing of my implant processors. I packed the Harmony in the Harmony dry case and put that into the AB travel case. I stored 7 or 8 extra AAA in the Little Things wallet thingy, and that went in the travel case. The AquaMic and spare UHP was packed into the travel case. But somehow, I forgot to take the waterproof cover out of Neptune case, so that got left behind. Dang!
I had considered calling AB to see if they would overnight a cover cap for me. Ha ha. I didn't. I'll just have to take my nephew swimming when I get back home and give the Neptune a try then. The quest for swimming with the Neptune has been delayed.
