J.,
There are tons of CSA farms who deliver all over the Cities. Here is a link for a long list of them from the Land Stewardship Project http://www.landstewardshipproject.org/csa.html
I used to go to a CSA Fair on Hamline's campus in the spring, but I don't know when that happens. Sometimes local coops or other places will host a fair in the spring also so you can come check out a number of farms. The site on the LSP website is good, but make sure you keep scrolling down as there's a ton of info after the directory part.
