Another issue is the holiday syndrome -- more people are actively looking for Easter egg hunt activities (an event with several hundred years of history) than are looking for spring fun, especially (as earlier noted) during Little League and soccer end-of-year events.

 

This does have a positive message for institutions: link with regional, national, international events in a mission-appropriate way whenever possible.  And, BTW, the news folks have to fill a paper or a 30 minute broadcast each and every day of the year.  You can get super cooperation for New Year's Eve camp-ins, day after Thanksgiving activities, last two weeks of the year, etc.  And that helps visibility for development, classes, membership sales...
