There may be a few spots that would could be not good between Calumet and Mohawk, especially just south of Copper City, but from the road crossings, there is still plenty of snow between Calumet and Mohawk. Actually, once you are out of Hancock, then all is pretty good. I cannot comment on 133.
I drove down to Houghton yesterday and took some pics of things in and just outside of the towns.
Here is the trail through Hancock. Pretty much down to the road grime.

The trail heading through $Bay is snowcovered, so if it were me, I would go that way!
Here is on the Houghton side, along canal drive.

I did not take any other pics because I honestly thought that other than it being old and frozen snow, there was enough to ride. Getting some fresh now. Probably 2-3" new since last night, a couple more today and an inch or two every 24 hours the rest of this week and weekend.
I do not get into the "is it worth it" game. That is up to each individual. But thought these would help.
