I'll be on in an hour or two as well. Do you have a general location in mind? (please, no more snow)
I won't be on, but from a quick look around the Dynmap, there's 2 spots that pique my immediate interest:
x=400, z=-2350, is nestled amongst some hills with a small lake, looking out over a desert and with a nearby jungle.
x=1900, z=1575, is straddling a short river between a desert and plains biome, with ocean on both sides.
I also like the little island at 1650, -1775, or the concept of just wandering in a different direction (further south or west, probably).
I had been intending on wandering off West from spawn into the unknown, but actually the furthest explored area due West of spawn looks pretty good, as does that area at 400, -2350. Both are coastal and with enough flat land to easily build on, as well as nearby treesources (it's a word, honestly). They're also roughly the same distance from Spawn. I think due West would marginally get my preference.
I guess that gives us two choices - due West, the area around 400, -2350, or wandering off into the unknown. I'll see what the consensus is from those online at the time of setting off.
