I'd normally jump right in and start making arrangments to meet up with you guys, but I just had an operation on my back and I don't know how long it will be until I'm back in shape.
The Docs say 6-8 weeks, although I feel better already. I should be in good shape by the end of the month.
Drop me a line a couple of weeks before y'all come over and maybe we can meet up.
Biergarten time usually gets going around April-May, so your timing is impeccable

My list of the best sights to see:
Deutsches Museum
Flugwerft Unterschleissheim (LW Airfield, with aircraft)
Zeppelin Museum Friedrichshafen (about a 2 hour drive, but worth it)
Pinakothek (Art, if you're into it)
Downtown shopping area (go on a weekday if possible, Sat. is crowded, closed Sun.)
Kloster Andechs (Monestary with good beer and food)
Schloss Neuschwanstein (castle - 1-1/2 hour drive)
Schloss Nymphenburg (castle in town)
Ammersee, Starnbergersee (2 big beautiful lakes 1/2 hour away)
Zugspitze (highest mountain in Germany 1 hour drive or train)
I hope I'm in shape to meet up with you by then.
