Ya'll be careful out there. Even those who aren't allergic can be subject to anaphylactic shock from these aggressive little boogers.
In town (our county seat, actually - Seminole, Texas), 25 people were injured last June from a swarm of Africanized Honey Bees. One man reportedly had 200 stings. Ouch!
Last year one of my fellow workers was attacked and wound up with about 40 stings before she managed to get back in her pickup. She was rushed to the hospital and given IVs to counteract the effects. She was a mess to look at for a few days, too.
Keep some Benadryl tablets with you to take as first aid between the cemetery and the hospital.
Good luck!
