I've also found some great looking deals in northern Kentucky on Craigslist though, there are quite a few people who raise grass-finished beef within an hours drive. I also found a pastured pork source in Henry County, KY, which is about an hour and a half south of me. I haven't ordered from them, but am considering it for the fall.
Right now I get all of my poultry and pork from Findlay Market, which is near the downtown Cincinnati area. The poultry is from an Amish farm not too far from the city (within 100 miles), though I'm not sure that it's pastured. The pork is "naturally" raised, and the sausages I can get there are made in-house, and have nothing added but spices (no preservatives or MSG at all) and are reasonably priced. Their bacon is nitrate free as well, and tastes 1,000x better than bacon I've gotten even at Whole Foods. Findlay Market also has a wonderful Spice counter, with almost anything you can imagine, awesome farmers during the summer/fall season with lots of different produce and locally made cheese, an Asian store, a Mediterranean store, local honey, local fermented foods....just lots of good stuff! I buy my meat there almost exclusively, though once I buy my cow this fall I won't buy as much meat.
I don't know about the 2nd Street public market, I haven't ever been there. I know there are many farmer's markets in the area, I just go to Findlay because it's a farmer's market PLUS a local market open year round, and it's close to me.
