Shahram and I left my house 8:45 Saturday morning and thanks in part to traffic problems got back to Salt Lake City 10:30 that night. We were both hungry since there was no dinner break, so we stopped for food and didn't get home until about 11:20 PM.
Although it was fun tournament, this felt for me like too long of a day. I remember in the last round I had a headache, probably from the tension in the tournament. (Ibuprofen should be standard chess tournament equipment.) Shahram commented that in the future he didn't want to drive this far to play such a long tournament.
On the other hand, I would probably do this again because I am such a masochist for chess. However, I was pretty tired the next day. Sometimes in the past when I would overexert myself I would get sick later. I am hoping that this doesn't happen.
