Last week we visited the Grand Canyon (south rim) and nearby Sedona, Arizona, primarily to hike. Noting that Prescott is fairly close to Sedona, two of us drove to Prescott in search of Fort Whipple, named for Amiel Weeks Whipple.
The first mobile mapping app we used got us to Prescott, but in a part of town with significant road construction. When we asked a flagman about Fort Whipple, he directed us to drive to the "nearby" Veteran's Administration Hospital. It took us only 5–10 minutes to locate the hospital. We finally located the Fort Whipple Museum inside the VA Hospital grounds.
