John,
If last Sunday was an indication, and it is supposed to be more windy tomorrow, I think it will be a factor on GRR. However, as I had never gone further than 2 miles or so past GMR, for all I know, it may not have even been considered windy last Sunday by those who frequent it. I wobbled once like never before, and it was during a gust from my side -- kinda spooked me.
