Yes, especially if the field is not a dedicated gliderport. This has

True, but in the case of Parowan I believe the NOTAM was required not
because there was a contest, but because the airport was closed at
certain times of the day because there was a contest.

In any case It's a good idea to use a NOTAM to make other pilots aware
of the contest activity.
