Battle of little big horn

When I was a kid in middle school we did a project for History class. It was to raise funds for the preservation of the battle of little big horn, Custard's last stand.
I became involved with it and I don't really recall what exactly we had to do for the project, my picture was in the paper and I was awarded this deed of trust.

I just came across this. Apparently I own 400 square feet of the battlefield. I think it is pretty cool myself.
