Boring important stuff: These pictures are mostly of friends or people in college. For practicality reasons I have gone under the assumption that if people have publicly made their photo available on the internet, they will not mind it being used here. If you are the subject of such a photo and wish to have it removed, just email me via jimjamjammin@hotmail.com.
