That's a crazy story! I'm glad you didn't get stung! I'm just picturing the wasp attacking the foam w/i your helmet...that's just insane! I'd be freaking out! I hate bees, wasps, etc! They bite, haha.I hit one when I first started riding that was so big I thought the car in front of me toss a ice cream cone out the window. I was real grumpy but could tell it was a bug when cleaning. Only time I have ever pulled off the freeway to clean a bug off my helmet.
The first year I was riding, I had my visor cracked to let in air and had a wasp make it into my helmet. Lucky for me he decided to take his anger out on the foam in front of my nose instead of my face. Pulled to the side of the road while watching him repeatedly sting foam a half inch from my nose. Toss my helmet off into the grass and a car pulled over behind me to make sure I was ok. I just pointed and said "wasp, big one" he gave me a thumbs up and pulled away.
