Down here in Sunny San Diego, we had great flying weather all morning. However, the local field had been over-watered and the grass was, well.... soaked!
Rather than tromp around in wet shoes, I took them off to let them dry in the sun.
Flying my Cardinal around I thought I felt this snap on my thumb. 8 laps later I heard the snap and definitely felt it! An arc was crossing from my handle to my thumb! We're in a very dry condition this week, and coupled with my bare feet in soggy grass I was getting snapped every 8 laps or so!
