This was my first one of these caps in a man hole. A little (lot) easier to find than those buried under six inches of dirt, especially when they are in a construction zone and are so well flagged! I was unable to discern all the numbers, so I sent ofth a photo. Thanks for selecting this interesting survey control point for your cache page ofth.
