Mitsubishi owners day. Held annually each Summer in Cypress Ca, Normal IL, and Camden NJ. This will be the 8th year running that they've held one.
originally started by their engineering group, after the first year they eventually convinced marketing that owners would attend them. I was at the first few shows but stopped going because very few 4x4s ever showed up (<5). https://www.mitsubishicars.com/MMNA/jsp/owners-site/owners-day.do
