There have been many types of exhibitions held at the Speedbowl over the track's 60 year history, however the above 3 exhibition events are the only ones that will be researched in The Vault.  Unfortunately many events were held on Family Fun Nights where feature racing was not part of the card and the press did not attend and/or did the track record the winners in some occasions as well.  Some of the events that have been excluded include:  Officials Races, Mechanics Races, Faster Pastor Races, Trailer Races and the various Match Races.  Those events may be logged in the Almanac section under the Special Events tab for that particular year, but will not be in the Exhibition Events section here compared against other similar events since it's proven to difficult to verify not only the results of those events, but when many of them were even held.  For more info on Enduros, Demolition Derbies or Women on Wheels events, click on the tabs above.
