Amigos in spam cans and other poorly fenestrated aircraft, I truly do not believe a task was set today for Lasham comps, as cloudbase is currently given at 350 feet!!!!!
HOWEVER be warned that even if the day is scrubbed and no task is set, this does not mean that no glider flying takes place. They've got nothing else to do if the day is scrubbed, so a lot of them may take off anyway and go local soaring! Practice, practice!
