How many local races (if any) have you been in that use chip timing? Did they work? We here in the midwest just had an experimental practice race with some riders pinned with chipped plates. It think the results were pretty good, but not perfect. Nat's don't use this system, I'm guessing too unreliable and too expensive.
Did the timing system raise your entry fees? Just curious to know what's out there and how far behind we are here in cow town.
