According to the TV Guide channel. the finals will start at 3pm here in CDT. They've been pretty accurate in my experience, so I will set my DVD recorder accordingly.
Depending on the weather (We've got snow forcast for that day here in Minnysoder.) I usually choose to spend the day outside, and catch it 0n the recordeing. I refuse to spend a nice day inside watching a "live" program."
I ALWAYS preprogram things, and never trust the automated sytems. If anything goes wrong, things get screwed up. Therefore, I program an additional half hour before the program,and an additional hour at the end. This system seems to work well, and has resulted in catching all of th races so far.
