If you pay for it and do all the work, you should get to keep it. If there are funds to cover all of your costs and you wanted to donate your time- maybe have a family raffle.
Or if reunions become regular whoever is in charge of next one might keep it till that time. Or is there an oldest family member who would love it-(warning it might disappear if eldest has it and passes away or becomes ill.)
I am going to watch this post and see what ideas people come up with. I am sure there are better ones than what I am thinking up right now.
