I tend to agree with Grit in that I would do everything in your power to avoid having to communicate with him about this. I would see if your friend in Washington would mind selling the snowboard on Craigslist or eBay. Give the possessions you have of your ex's to his friend and leave it at that. As for the bindings, I would do nothing for the time being with them if your friend doesn't mind holding on to them. Perhaps he/she could communicate with him directly to figure out a mutually agreeable solution. And by mutual, I mean as between the two of them. Do not participate in those negotiations and make it clear to your friend that you will not be part of the solution. I am not suggesting at this point that you just sell them because, well, do they belong to him. In time, I think you could make a case that he simply abandoned them if he makes no attempt to retrieve them, but I'm not sure that time has yet come.
