Shubie was great last night! Even the non-plowed sections that we rode were packed down well and fast.
Spider was a bit tough going, but if you stayed in the groove it wasn’t horrible on a 4.8" tire. On a 27.5+ tire it was tough to keeping going. Some of the trails had seen traffic and may see more today so this evening may be decent on a semi-fat or bigger tire if it stays below zero. I think it would still be too soft/unpacked for a regular width tire.
