The lake has frozen and many people are skating/skiing on it. Hi, Do both skating and skiing make sense in the above? Thanks.
Perfectly all right providing it has snowed as well. There are about 180,000 lakes in Finland and people ski on them every winter.
Jesus, if the people are wearing these http://www.orssnowshoesdirect.com/ors-ss-images/other_products/karhu-meta-skis-lg.jpg they are skiing; if they are wearing these http://www.germes-online.com/direct/dbimage/50120034/Ice_Skate.jpg they are skating.
Well to be precise, they are skiing on the snow which covers the frozen lake. They are not skiing on the frozen lake itself.
