Just be sure to lock your car. There aren't too many high paying jobs in the area (year round), and 'boys will be boys' when there's nothing else to do. I don't want to sound discriminitory, but all I'm saying is that crime happens if you're not smart about things. Park your car in lighted areas. Lock your car, and don't leave valuables in plain sight inside your car, either.
Whiteface mountain, which is the main Lake Placid ski destination and the hill that held the Olympics, is a very icy hill. The wind blows across it and any snow that is there in the morning is gone by the afternoon. If you're skiing there, make sure your skiis are sharpened. The picture is of a friend of mine who decided he didn't need snowboard lessons. Notice the sling.
