We were traveling over the Garden City Skyway towards Hamilton at 2:30pm today when I noticed this odd looking cut through the clouds. It caught my attention as it appeared to (unlike an airplane vapor trail) arc to the ground. My son looked for where it started and said it just seemed to start directly overhead. I had him take a few pics with his cell. These 3 are about 5 minutes apart each. Would love to know if it was a meteor or the like.
