Bad Decision, Good Decision

At Gullion yesterday.
Bad Decision: A long hike (1hour)with the glider to take off because road was closed due to icy conditions. Very foggy conditions and should have known it was not going to be flyable. Long hike back to car (another hour).
Good Decision: Mist and fog cleared temporarily and was tempted to fly but then visibility went to zero. Glad I wasn't in the air.
