For those that are NOT local, please book a room for Friday night at the Comfort Suites Dayton-Wright Patterson (across the road from the USAF Museum). There is no group rate as many attendees are local, so we do not have enough for a group rate.

I will be arranging a group dinner Friday night for those staying in the area for the Saturday tour.

For those that fly in to KGDK, DPA will provide transportation from the Airport to the Hotel on Friday afternoon following the Hartzell Tour (~3pm) and from the Hotel to the National Museum of the Air Force at 8:45am Saturday.
