OK did some zooming around, and I think I see what is being installed, in the third photo down, if you zoom to the stack of water pipes just past the building on the right, I think that is what is being put in the ground, the gas main is clearly up by the road, and is also marked with yellow paint strips, and the yellow flags there have writing on them, the flag by the split rail fence doesn't as nether does the one by the drive next door, but the locates and these pipe does go down the street.
Ok Dick tracy mode off.:grin:
If you have explorer 8.0 to zoom in, hold down the CTRL and hit the +, to zoom out CTRL and hit -, to move around use the arrow keys.
You can zoom to a max of 1,000 times this way.
