Narrative:

During en route operation from iah to btr I flew over lake charles at 7500 ft. Before takeoff I checked WX and NOTAMS. (NOTAMS for departure and arrival airports since navaids were not needed.) I was monitoring approach frequency but not in 2-WAY communication. Nothing unusual about the trip was noticed. The following day, I found out they were having an airshow at cwf, chennault. I may have entered this airspace on the previous day. I should have received a more complete briefing and had flight following.
