If someone could turn off the car with two flashing red lights (from webcam perspective) N of the lamp post at 44°27'38.8"N 110°49'54.9"W, that would be greatly appreciated. That disco light is very distracting, moreso than virtually no visibility into the basin, especially since it's continuously doing it. |

Just an FYI since I have not seen this reported yet: there is road construction taking place between Old Faithful and just north of Biscuit Basin. It appears to be a continuation of the work on Craig Pass last year. At the spot where there was that prominent bump north of Biscuit, there is work underway with one lane closed and a pilot car. My wait there was about 15 minutes. |
