I am editing a series of videos on our flight of eight from Central California to Oshkosh and return in 2004. After leaving Oshkosh in marginal weather on our way to Fairmont, MN, we stopped at a beautiful grass strip. My notes says the airport code is 2J4. I can't find any info on the web. Anyone familiar with this great stop. I suspect it is in Minnesota. Thanks for any help.
