Hope I don't get myself in trouble here, I'm not posting as a USFRA official. Just hopefully shedding some light on this subject.
You probably will not see a pre-entry list for WOS, for a very good reason. When the list did get posted in the past, some creepy jerk or jerks, took it upon themselves to start calling the teams on the list, and tell them that the WOS was cancelled, when in fact it was not.
I can see that if you are traveling a long distance it would be nice to know if it was, but if you get a phone call, find out who it is, and make sure to call the USFRA number and get an official confirmation.
Jim B knows the salt, and it would have to be pretty bad before he cancelled a meet. The first year I ran my car, after spending night and day, 7 days a week getting it ready after my retirement. It rained real hard the day before tech, there was 6 inches of water from the pits to lands end.
Jim made the decision to tech at the lands end, and start the meet one day late, mother nature co-operated, the salt was great and I got to break my valve train after all, didn't have to sit in anguish for another year to do it.
