Good post Jim. You could even take size out of it and say specialization. I always wave at other guys and I get a few waves back. I regularly work for another larger company doing rip outs since they don't have the equip, adds thousands a month. They will also send me leads they receive out of their area since I'm a few towns away.
Unfortunately at the supply yard at 7am Monday I see many more scowls exchanged between owners than smiles. Not from me though
