I'm game to help out. I tried calling Famous Daves and Grand Pines and got a "huh" at one and a not sure at the other when asking about the Winter Fly-In for 2007. I'd say scratch that from the list as a primary fly-in. If dates re-appear we can put it on the calandar as an "affiliated" (my term) fly-in for people who go anyway to get credit. For us the wife has absolutely verboten on landing on the lake and I'm not too keen on it either. Driving when it's January and you can personally see and assess ice conditions is one things. Landing ice unseen is another. Plus it's unclear if that would be covered by insurance, so we'd end up going into Sawyer County anyway.
So I'd guess I'd say let's start to plan for a North Central BAC fly-in in February. That will still be a nice "winter" Fly-In but with slightly less of the near and sub-zero cold that complicates winter flying but early enough to stay clear of the low and mid-level icing we get Spring/Fall. Somewhere "up North" would be interesting. Start with suggestions for airport and timing. Tie-in with a local event helps make the day interesting but isn't required.
Aitkin Airport at leasted used to have an annual Valentines Day Fly-In. There is an old web page at
http://www.aitkinaviation.com/valentinesflyin.htm.
We could follow through with a Metro-located event in the summer. KMIC had an open house on Father's Day last year that is supposed to become a regular event. Other local aviation events in the metro or near metro every year are Wings and Wheels in Osceola, WI.
MN DOT Aeronautics division maintains a Minnesota Fly-In page at
http://www.dot.state.mn.us/aero/avoffice/events/fly-ins.html and offers downloads of airport manager addresses to send out fly-in flyers for posting. The listing is sparse but usually fills in as the year gets moving.
The Anoka EAA chapter has a more complete list of EAA sponsered fly-ins at
http://www.eaachapter237.org/flyins.html, including their own. It's a 2006 schedule but gives some starting points for searches.
We should probably steer clear of late July and Early August to to avoid Oshkosh and BAC to OSH if it comes together.
