I'd probably work with some people and rush some gear so that I can get started on some big projects. Not that great with redstone, better than I was when I took a break from Minecraft. I like my builds to look good, so there's that. I'll probably end up AFK farming for enchants occasionally, unless anyone's offended by that.
Intentions: Build far from spawn to avoid griefers and have plenty of room to mine. Find spawners and make XP farms, search for Nether Fortress and get Blaze Rods, Raise cows and chickens for Leather and food and make some Redstone devices.
Am on Pacific time so "Late Night" is in the eye of the beholder.
