Also, be aware that someone rode their bike down the first half mile or so of the Perimeter (from the parking lot, to the West side, and straight north). I caught my skis in that rut several times. Please spread the word that bikes are not allowed on the skate track. They're even worse than classic skis (which aren't good for the skate track either), since the bikes leave a much deeper rut.
The descent at the northeast corner is very ice, so take it easy there.
If you get out before it gets warm, I think you'll have a satisfactory ski.
