On the weekends, I walk 5 miles in the morning for exercise. While walking on the sidewalk next to Rock Prairie, I saw the manhole cover with the word "Vulcan" on it. It struck me funny, so I saluted it.
I quick google search, says the Iron works company has been around since at least 1988. I'm guessing they were inspired by Star Trek.
Live Long & Prosper
K.c.-ya!
