FYI, for east coasters, I understand that Bay Airport (right across the Chesapeake Bay Bridge from Annapolis, MD) also has one or more DA40’s for rent.
Having trained in a DA20 several years ago, I think the Diamonds are a real hoot to fly and hard to get into trouble with. Two minor regrets about the DA40…would like to see 20 more knots cruise, and the baggage area is mighty small and awkward due to the DA40’s empannage design (skinny!).
