Just got out of the most recent TEDxNashville TEDxChange session. It wasn't as great as last time, I believe the sponsor was Healthways and it felt heavily like a sales pitch for them sometimes. But, learning about ShadeTreeClinic.org and NashvVegi.org in Nashville was great. Shade Tree Clinic is a volunteer run clinic in east Nashville for the uninsured and they have a community garden as well it appears.
One of the speakers at today's session was recently one of the big TED talk. Here is his talk there.
