Dave- The 'Bay of Quinte' jet rally dates are yet to be confirmed for 03, but this years 02 jet rally was 14-16 of June and I would expect similar dates for 03. So if you plan on visiting, June would be best for Canadian jet activity. Here some pics. of 'Bay of Quinte' 02 although mostly rained out we still had fun- http://www.TJT.bz/newsdetail.php?news=18&page=0

Winter flying is not too common here as the winter weather is not always cooperative. I am actually getting myself a park flier soon so at least I can get a quick flight in occasionally weather permitting. That said we do get the odd winters day warm/clear enough for jet flying, unfortunately coordinating the good weather with weekends is rare...
I always keep my batteries charged though! on the odd chance, of a clear warmish Sunday : )
