Wow, I went on vacation for three weeks, and missed out on most of the fun. IFR reminded me of a mechanic we once hired, he immediately came on the two way radio, and commented that all his equipment would run like a fine swiss watch, thats how good he was. well from that day on whenever he would be dispatched to a call, the next hour would be all the guys making tick tock sounds into the radio. He quit not long after. After 27 years in the business, one thing i do know for sure, If someone says he knows it all and done it all, thats the last guy you should call for help. I have helped quite a few guys with this personality trait, I always get a kick out of them.
