I'd love to see a multi day event at haubstadt. That place is awesome and I like multi day events with no travel. I make the 3 1/2 - 4 hour drive down there several times a year and it's always worth it, and the drive would be that much more worth it for multiple races. I don't know if it will ever happen but we can always hope.
Lawrenceburg would be a fun but dangerous place for multi day deal. We'd all go broke at the casino during the day
