I minored in French in college, and am a fairly proficient reader of French. For practice, I recently finished reading through the Harry Potter series in French, and got myself to the point where I could read at nearly the same speed that I read English.
The issue is that my conversational French is well behind my reading ability, due to lack of practice. Given that I live in a part of the US with basically no French speakers, how can I best improve my conversational French, both in listening/comprehension and speaking?
