These guys (and girls, there were at least two) got close, really close, and yet there were no accidents. A testimony to their prowess on two wheels.
I switched up to my 50mm for a few shots but was unsatisfied with the results, so I stuck with the 80-200mm. Most shots were taken at either the 80mm range, or 200, rarely in between. My camera now needs a good cleaning with a dust remover.
