I've always had good luck with Vittoria Rubino Pros. I used to get pretty good deals on them at probikekit.com, but I haven't purchased any for a while. The "right" tire depends, in part, on what kind of roads your ride. If they're in bad shape and/or you encounter debris and the like on a regular basis, you might want to go with a more puncture resistent tire.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
