Stop in for a cup of coffee

We were making road materials and concrete materials for a Army Corps of Engineers flood control project in Ontario, pretty much right across the freeway from Ontario Airport. One Friday afternoon in the fall I'm getting the rock plant shut down and continue to hear this odd noise after most of the machinery is shut off. :wtf: is that noise? Wait a minute that's a Nitro motor!
Then the little light bulb lit up, Ontario Motor Speedway was just down the road a piece. To my foreman on the walkie talkie I say "Leroy! It's World Finals weekend at Ontario! :wtf: are we doin' workin?" :lol:
