Capt Fathom. Quite right - on both counts - "memory" is going and no "airports" between RK and MK.
Looking at my logbooks again and it seems like RK-BN-GLA-RK was the paper run at that time - not even GYP, MYB and Bundy.
RK-SLW-OGM-MLB-RK was the clinic run other than WBA.
....and lots of RK-GKL-RK...
