Yellow jackets. I ran over a nest yesterday afternoon before I knew what was happening. I was riding the WB with my Jungle Wheels in 4th gear and I saw a bunch of flying insects swarming around a clearly defined hole in the ground. I was making some nices stripes until then. I was still mowing and looked back to see what they were and my stripe went all to hell. I was out at the weigh station on southbound I-77 and it's a really long stretch of grass. I cut the lower side and when I got about 4 mower widths away, I pumped it up to 5th gear! I was going to do something about them but I didn't even get to finish mowing because of lightning and rain. They'll be waiting for me next week I guess. Man, I hope they're not as bad as they were last year.
