It's been a few years since I've livee in St. Charles County, and correct me if I'm wrong, but isn't Francis Howell a year-round/cycle district, while Fort Zumwalt is a traditional Fall ---> Spring school year? A logistical nightmare that I chose not to attempt in our short MO stay, but looking back on it, it makes alot of sense.....
If I knew then what I know now, I would probably have chosen to live in St. Peters instead of O'Fallon (Dardenne Prairie) where we lived. St. Peters (if I'm remembering correctly) is Fort Zumwalt, and has a GREAT Rec Plex (
St. Peters, Missouri: REC-PLEX/Recreation) Now I'm back in New England, and sure do wish there was something like this in the area.
Anyway, enjoy your stay in Missouri

Visit the wineries when you get a chance, cycle the "Katy Trail". Visit the Meremec Caverns--great fun the first few times. Visit the St. Louis City Museum many times, along with the Zoo, & the science museum. The Arch/museum, again, fun the first few times. While I'm happy to be back in New England where I belong

there are a great many things about Missouri that I do miss!
