Waterlogged Drift Wood

[MyFishHasRabies]

This morning my friend called and asked if I wanted to go looking for driftwood with him. I agreed. I assumed he wanted to beautify his house and yard, but he was just looking for some smaller pieces for his aquarium. That was easy enough, so we took a drive around Lake Bemidji and stopped at all the public places we could. We found some, but at the last stop I found a 2'-3' x 10" log. The grain is tight. It looks like a hardwood, possibly maple. It's not old. I can tell it was cut with a chainsaw.

Does anybody have a clue what I can do with this thing? I went through the trouble of picking it up, so now I gotta make it worthwhile. I have a chainsaw. I'm thinking about cutting it in half and seeing if I can't make some kind of outdoor "I Live Here" sign, but with a chainsaw that is easier said than done. How long should I let it dry? It's soaked throughout.

I can see now that it's almost as long as a pallet so it's almost four feet in length.

here are a few bad pictures of it:
