I'm sorry to say I think I need to cancel the tangent-bundle geometry lecture today. It's taking me much longer than I had anticipated to prepare my talk for tomorrow, so I think I need the time to finish that. So I'll cover more of the background tangent-bundle geometry in my talk tomorrow. Hope to see you there!
