Should have posted this little thread earlier...
On Saturday, I took a road trip out to the DM52ax/DM53aa grid line, along US-70 northwest of Safford in Graham County AZ. My first road trip out of town in about 5 months, to a spot I have visited many times for satellite operating since 2008.
@guardeddon Most Garmin GPS receivers can display Maidenhead grid locators, and the Trip Computer display can be customized.
