We know another couple well, they keep bees about 20km from here. He is a pharmacist, she works in an office in town, they have 6 colonies on their property. He decided to just keep a kit around 'just in case', the type where you have to draw into a syringe then inject. His rationale, if anybody around was having a reaction, he is well versed in how to do the process and apply the injection, so no need to spend the extra on the auto-injector.
Wind the clock forward 4 years, they are out in the bee yard one Saturday afternoon and he got stung, has never had a reaction in the past
