While my wife helps me installdrivetrains and is very capable of building her own engine, constant car stuff she can't do. The best thing to do is do something after the meet. While she may not be there, I send her shopping. As a normal activity she'll read a book or garden.
When we have done Carlie, it is always dinner and something else as well afterwards. Movies, touring the town or state area, river fishing in which she like to do a lot.
When I went with my old car club, many of the wife's got together and went elsewhere together and did stuff. Have your wife's hook up! It's better than frowns, pouts and complaints.
Good luck
