WHHOOOP ! wow...
Tamrock just stepped up to bat...
And I THINK just nailed that straight otta the friggin park... parking lot... and into the neighboring street.
I've also found something similar to that except it had a screw placed in it. Mine was about an inch long and 1/8 of an inch wide so much smaller than your find. It may be some sort of building supply, but I could be wrong! My find was steel.
