Yes, there are places you can mail a letter underwater. Gadling lists five of them. Link -via Dump Trumpet

I’m a bit bummed that you can’t order a postcard from there and mail it to yourself. Oh well, looks like I’ll have to go there and do it myself.
Moe, that’s a great idea! This would be an easy way to generate a little extra revenue for the local communities.
