Yesterday, as I was pushing the pace on my MTB getting a good workout, I bumped into a yellow jacket coming the other way- with my mouth open. I didn't see but felt it, exhaled hard, tried to brush it away, and felt instant pain on the inside of my lower lip. Within an hour my face was swollen like a pumpkin. I was just plain lucky not to have inhaled it. It is a drought year and they are always more numerous in dry years, also more aggressive as the summer turns to fall. Now, after a day and a half of benedryl and ibuprofen, it is rapidly subsiding. I hope nobody else has this experience.
