Susanville traffic on a 4th of July holiday weekend?

[goneskiian]

Contemplating a run from Reno to either Mt. Shasta or Klammath Falls this next Sunday. We'll need to spend some time in Susanville either way. Just trying to gauge how busy it might be at those HPWC's at the Red Lion or the J1772 at the casino.

We're traveling from Mammoth Lakes to Seattle and are really hoping not to have to back/side track over I-80 to Sacramento if at all possible.

Thanks!
