Now to figure out whether to head to NYC straight from the weekend in Maryland, or come back to Ithaca first, and which of various friends in NJ and NYC I should try to visit this time through. :-)
Tempting to just stay in Maryland until Monday, drive up and stay with someone in NJ that night, then dive into Manhattan for the Expo and stay with my folks the rest of the week. As long as I plan right, easy enough to go from MD to NYC without bouncing off Ithaca. Just have to remember a) not to promise anyone a ride down from Ithaca, and b) to pack for a week before the Maryland weekend!
