I have eleven remaining ~30-minute lectures from the Barbarian Empires of the Steppes course, which is five and a half hours. Madison to Ithaca (uh, that's Madison NJ, not Madison WI) is usually ~4 hours, so even allowing for horrendous traffic delays, I should be fine. :)

I will need to acquire a new set of lecture CDs for when I return the dog in September, though...
