Narrative:

Fog rolled in on my balloon at X:00 ft MSL. Was unable to find a landing spot so I had to continue flying approach 300 ft below ceiling. Hard to predict fog. Callback conversation with reporter revealed the following information: the reporter states that there were 3 balloons flying together, all from the same company. There have been no repercussions from this low flight.
