While the 1991 trip brought me to the western parts of the US and Canada, the 1993 vacation was a bit of a mirror image of that tour. It started with an extended weekend in Toronto, followed by a week in Philadelphia with a short excursion to Washington, DC. Then it stopped being symmetrical, since SIGGRAPH'93 was in Anaheim, so I made a one week detour to the west coast, before flying back to Toronto for a week, from where I made a short trip down to Niagra Falls. After that I flew over to Halifax for a two week rental car trip through Newfoundland.
