I think it would be a nice meeting for the summer would be to all show up as a group to one of the Cars and Coffee meets they have. Lots of other car clubs have done the same thing and it's quite impressive to see 10 or more cars show up as a group.

I've gone quite a few times and it's a great event. It's early in the morning and held at a really cool place, Automotorplex.
I originally organized this as a Galant meet, but other Mitsu enthusiasts are encouraged to come. It's a great event if you love cars.
