B.O.M. isobar map indicated wind good on Wed but rain on Thur (they got it right), (apologies to Laurie).
Blokart in boot, 20 min drive, arrive around 3:15 pm, have a scan and point face into wind. Opinion, yes, there should be a ride both ways. Try upwind first to assess how adventurous to be downwind.
Take photos fist to verify post. Just get 4 pics before camera shuts down because darling 16 y.o. daughter has flogged the good batteries out of camera so she can get all important shots of her and mates doing stuff on her camera!!![}:)]
