Nah - Jimmie is a California boy, and from what I can see, no relation except maybe back in the pre history days.

EOE NASCAR - I looked on AMAZON.com and not there, at least yet. Since it was a show just for TV, probably never will be a DVD.
Too bad your guy Marcos Ambrose had a bad day with car problems yesterday - he even lead the race for a few laps (then I snoozed in my recliner until the last 50 laps - dull race - and the next time I looked he was 40 laps down) ended up 35th, "only" 63 laps down.
