Yesterday's ride home was a bit of a challenge on an un-plowed/un-treated MV Trail. The snow was crusted over with ice in many spots, pock-marked and rutted and, had drifts of powdery snow that were probably 12 to 18 inches. I was able to manage a steady 12 mph where there was still a few inches of powdery snow even where the drifts came up to my bottom bracket and clogged my pedals and cassette with ice/snow. I saw only two other riders (on mountain bikes) and managed to get home without dumping it. I slipped onto the grass a few times as I was riding as near the edges of trail as possible, that's where the best traction was. I made it home in about 50 minutes and proceded to shovel the front walk. I knew that the trail would be an icey mess this morning and, didn't even attempt it, will probably take the Metro the rest of the week as my rr. hub is loose and I have to get some cone wrenches to fix it.
