I just rode it today on my way in. It is good (going southbound from Diversey at least) until Oak St;
then it's not so great. I walked to about Chicago then rode the upper lip sidewalk; etc to Ohio St.
Lakefront Path conditions, Sunday morning February 7, 2010 from 57th St to the Aquarium: mostly clear, dry pavement, with sections of clear track through snow and ice sections. About 30 yards of solid, rough ice at the north side bottom of the rise at 35th Street. No clear track through this mess, consider walking and take care descending going north. Also ride carefully under the tree overhang section around 38th Street.
