What a nice surprise! A few months ago I was contacted by Valve and they mentioned that they were including pl_Hoodoo in their next update. Because pl_Hoodoo features my ambulance Valve had to buy the ambulance from me if they wanted to use it in their update. I said yes, filled out some paperwork and about a month later it was released. As you can see in the image bellow I was listed as one of the contributors to the map.
