Streaked Sky

After posting several "sun photos" while at the beach last week, I was a little hesitant to do another today, but the sky was too unusual not to share.  I took this photo from the parking area at a gas station/convenience store while traveling to the NC mountains for a regular 6 month dermatology appointment on Monday.  Most of the streaks in the sky are from airplanes (there is a new small one in the lower center of the photo), but I don't know what created the larger streaks in the sky.  This traveling might limit my comments but I'll catch  you later if I miss you in the next day or so.  Your photos are too good to pass up.  You might this one in large.
