Mono Monday -In Motion

This is the first time I have tried panning technique so thanks to Carolina who set this topic. I just stood on the side of the A1 dual carriageway and took shots passing vehicles with something like a 1/30th shutter speed. I was probably a bit close to the subjects so usually only one or two shots in a sequence would be sufficiently sharp. Still you have whetted my appetite and I will probably try out this technique again.
