Airport Rd Proof-of-pudding

I was a little sceptical about my under-16-minute time outbound to Airport Rd, based on a 17-minute time from seemingly little-less effort.  So today I tried again a "maximum-effort" walk out.  15:47!  I tried a little harder to keep it up on the way back, for a return time of 16:58 and a total of 32:46.
