I feel for you, I'm allergic and swell up horribly. Let me tell you what happened to my Grandma in about 1979 in our rodeo arena. At the time my Grandma was 68, and during the barrel racing she would take care of raking around the barrel on the left so it didn't get trenched out and cause a nasty fall. One rodeo she went out and started raking right after a rider did the pattern and suddenly she threw down the rake and started stripping! She kicked off her boots, dropped her pants and ran hell-bent-for leather for the back gate that led into our barn area. My Grandad was the announcer and he was there saying things like "Jo! Jo! What are doing??? Put your clothes on Jo!! Don't do that!!" Turns out when the rider went around the barrel it stirred up an Army ant hole, the big black and red ones we have here in NM. When she walked out they went up her pants, into her boots, and just kept right on traveling. This was in front of a couple hundred people at least.
