I think the deciding factor was the cold headwind, a definite shock to the system for the birds after what has been a mainly warm start to the season.
Return wise we had a good race from Messac 208mls, but the birds were really showing it when they came, looked like they had flown a hell of a lot more than 200 mls.
As for the Portsmouth lib for the NW fanciers, the birds did eventually get away with no sign of any batches locally during the afternoon, and no reports of strays in local lofts. I would have thought the later libs would have fared better, but the there was reports of appproaching rain later in the day which probably was the deciding factor in letting them go at 8.00.
How did the later libs fare?
