MOT, Tractor and Wokka

Took the MX-5 to the main dealer in Gloucester for the MOT this morning. Glad to say it passed, after having a sidelight bulb changed. I check all my lighting regularly so that bulb must have gone in the past few days.
While it was being inspected I walked to a large pet store to pick up a box of dog food for Jonty. While waiting to cross the very wide and busy intersection the tractor came along. That's what you get for living in a place like Gloucester City :-)
The photograph of the Chinook was a late afternoon, just as the light was starting to fail, opportunity. I heard the noise, it's unmistakeable and it's also how the Chinook got it's nickname "WOKKA WOKKA WOKKA WOKKA". It's pretty much the noise they make.
