It's at a great level now for IK's, Kayaks, Pool Toys, Packrafts and rising. Should be a good weekend. Road from I-70 to McKay flats / Red's Canyon junction mostly 35 MPH. Dusty. Same for down Red's canyon to the put in. McKay flats / Red's Canyon junction towards takeout is the same until it meets the other road from the put in, which isn't so good. Heading from there to the takeout gets worse quick. It's a dashed route on the maps. I did it in a Corolla OK, but with a couple of minor undercarriage scrapes from being loaded. RV's or trailers would not like it.
FWIW, at the takeout camping spots next to the airstrip, I took my Arduino-based Geiger Counter and measured 10X background radiation just standing there. 250 CPM. It was chirping like the bad part of a 70's Sci-Fi movie.
I normally measure 25 at my house, and Denver, and most other places. Highest reading before that was 45 CPM in the still natural Uranium belt below Telluride. The airstrip was made from the tailings of the Uranium mines. In the 100 Yards further to the parking area it fell back to 25, or normal background radiation. I imagine possibly much higher readings if going in a mine.
I know it's cumulative and 1 night won't make a difference, but if some critical bit in me gets flipped from it ... Like the ' All of a sudden hate Beer bit ' We found a different camping spot. Down the rough road to the river is good. It's OK to drive down from the airstrip to the river now and camp there. Or at the parking area before going down from the airstrip if the road is too rough.
