Don't let those little SOB's fool you..... they are fast.
Years ago, I was cutting back side....I was on a hill and mowing down, verses up. I stirred up a nest and they were buzzing about. Pointed downhill, I simply pushed clutch in and gained speed coasting verses taking the time to stop, clutch, change gears, get moving again.
So I'm rolling down hill at a bit of a 'bouncy' pace... wonder what's going on behind me so I turn around to look back. There was one of them 'keeping up' with me.
In a blink of an eye, I had the thought go through my head "thank God the little SOB isn't gaining any ground on me"....I look to see how much further/longer I can coast... I have plenty of room. Turn around again to see if I'm out-pacing the little SOB and nope, he's keeping up with me.
All the sudden, he went from 10-15' away, goes into attack mode and in a near blink of an eye, BAM, covered that distance and nailed me on the forehead as I recall.
He wasn't in genuine attack mode prior....he was merely loafing along, probably chasing me away and when I got far enough, he decided to add some insult to injury by nailing me with a sting so I might know what they can do if I ever go back.
It really astounded me how he instantaneously covered that distance.
