Hi Mary! Good to hear of an urban CSA being created in the Birchwood/Columbia area! I noticed you've posted many identical CSA notices on many of the TW groups. The one that may make the most sense to post on would be the group Walter started for farmers offering CSA's, located at: http://transitionwhatcom.ning.com/group/csashareprogramsproducers
You can add onto your TW personal page about the work you do and your website link. Then folks can go to direct to your page and leave you comments or questions.
