Yeah, I should get to Oshkosh sometime....it's just across Lake Michigan. Considered renting a C-172 for a weekend and going there, but never did.
Funny you should also mention Lakeland, Florida.....I just flew over it last night (in FS2k2) on my way to Miami Intl.; I'm doing an 'around the country' flight in the Beech Baron (counter-clockwise from Michigan.....also landed at Oshkosh on my way!).
