I will begin by revisiting a VLA observation of the radio jets in NGC315 that was made twenty years ago almost to the day. I make this my starting point partly because it gave us an early hint of how the VLA could impact the study of AGN jets, and partly because it involves (yet) another "Barry Clark story". In what follows, I will not try to summarize all of the different ways in which the VLA has added to our knowledge of AGN jets, but will focus on questions about jet velocity fields and the differences between the two primary jet "flavors", using NGC315 as a guide.
