I left the house this evening with the car and drove past the church right at the bottom of our residence. There was a whole area cordoned off around a fresh dig and a roll of yellow conduit. The dig was ready to go under the exact street that we would have to cross to get to the exchange.
In France (and probably other places) builders are required to use a certain color of conduit to put in the ground so that other workers will know what it is if they come across it in their own digs.
I knew that red was for electricity and blue was for water but I wasn't sure what yellow was for. If it was for telecom I would have taken the day off tomorrow and asked the construction crew how I could possibly lay my own conduit quickly next to theirs. If I could get across the main street the next little bit to the exchange would be much easier.
I was already planning on calling Vincent MONVILLE for something unrelated and thought if anyone could tell me what the yellow color represented he could. I asked him about the conduit and he explained that is was for gas. He chuckled when he said that it's not a great idea to try and mix fiber and gas. :)
