i done a dance yesterday not from welding but from cleaning out a ditch with a mini excavator no cab,pulled out a wasp nest about the size of a melon,i didnt know this until the burning sensation on my arm,back,leg,head,and it was the mad run dance to the disco i think i was lucky when you see the amount of wasps flying about sorry to hijack your thread but it might bring a smile to your face,chris.
