Not a lot of ice as of yesterday, chains will not help that much. Drifts are mildly crusted and crystalline so mometum and wheels speed will be your greatest assets and of course the higher your underpinnings are the better your chances. Drifts up towards the top are 3-5+ feet deep and plentiful. Choose your trail breaker well! Still two weeks before the S&P run so a lot can happen to change conditions! The trail should be broke before then but wind can erase tracks overnight. For an example, the large drift at the playground is over 6' tall this year and the crust will not support a person!
