I did the TT two summers ago on a Loaded GS. I didn’t find any sand holes, but graders were working 3 different areas. Where they were working, it was like riding on 6” of golf balls for many miles. That and the berms they make were the biggest challenge for me. There were steeper hills with deep grooves toward the end. I went at the end of June, I believe the road hadn’t thawed very long. I was wondering if perhaps a little later in the summer and perhaps they would have smoothed these deep ruts out...very difficult in a loaded GS.
