Had a tyre blowout on the A5 near Milton Keyne's NE turnoff. Called the RAC at 1138. RAC driver-technician Paul found me just after 1600. He showed me the scant info placed online for my location. Granted, I had an American phone which made contact and location difficult to determine. Finally able to speak via phones. (I was stuck on a busy dual carriageway.) Anyway, Paul attempted to repair, but it was too badly damaged. Called Jacob of Skelton Tyres, found replacement. Jacob and Paul had me traveling again by 1730pm. Thank you, Paul and Jacob. FYSA, it was an extremely frustrating afternoon.
