My friend Ben was posthumously awarded his PhD in economics from UCSD this past weekend. The UCSD economics department has a tribute page that is worth reading here. Also, the department and Ben's friends are raising funds for the Benjamin C. Horne Memorial Prize to further research in Ben's areas of interest: peace, international cooperation, development, and environmental protection. You can read more about that here; I'd love you if donated.
Another good cause only slightly less close to my heart is the CDT. The previous non-profit that partnered with the Forest Service to manage it went belly-up a year or two ago, but there's a new group, the Continental Divide Trail Coalition that is trying to take over; their campaign is here.
