Are we sure we’d get better the next time? Good question Bill.
If we assume that the average wind speed prediction for this weekend is less than 10Km/h then that effectively equates to no flying this weekend. In that case I'm thinking that no future weekend could be any worse, from a flyers point of view. :?
On the assumption that a future weekend might have higher wind speeds, and on the basis that it couldn’t be any worse than this weekend, I say postpone.
That raises the question of when to have the ISR Glide-In. Bearing in mind the Shannon club have their Glide-In on the 13th June, we have the choice of next weekend or the following weekend. :?: If we put it off to the following weekend that puts us only a week away from the Shannon’s do. (Assuming they don’t postpone theirs.)
FRED,………….(oh guru of matters gliding) guide us through this maze……………..please!
(Just to add insult to injury, I was on the south slope of Big L today with 50 - 60Km/h winds at the ridge.

As Fred would say, “There were lifts everywhere!”)
