In all the excitement over the move, I forgot to mention that my Sirfetch'd hit best buddy a couple days ago. I've moved on to walking Killmonger, my shiny Mightyena. (Other candidates I was considering: Ronan the shiny Umbreon; Diss Track the shiny Cradily; shiny shadow Venomoth; shiny Milotic)
Meanwhile, my alt phone has largely been working properly, and I'm up to 94 Sandile candy. Only 30 more candy to go! (150 km) Probably around three more weeks of walking, since I don't always carry my alt phone around.
