Don't plan on finding a job in Syracuse - we've done a good job of taking advantage of the current "downturn" in the economy so we're shutting all the manufacturing facilities we can and putting our people out on the streets. We can't compete with China in manufacturing anymore, but we sure can make some good beer!
