Gary - thanks for commenting. Yes, a round shape would give you a looong ride - infinite loop :-) Maybe the term "Infinite" was a bad choice.
Keith - thanks for your comment. You are correct about the sharpening - as you say, not sharp but soft - I chose to post it anyway because I hoped it would be perceived as motion - the bicycle and dog moving into the scene. Shot at 1/100 sec. and no panning .. I'll have to work on that. The rest of the scene seemed "sharp enough" for the small size (1000 wide).
