My last Huey ride(s) were only about twelve years back- while working at the HQ of DeWitt Army Hospital I was "asked" to get some aerial photos of Army Dispensaries and Primus Clinics in the Washington AO. Lotsa fun, but I couldn't get the guys from Davison AAF to low-level at ALL !!
For me, a day of free Huey rides is a million bucks.
Have fun, Tom- give the folks our best!
