I think road is being plowed for the first time so people can use the cog railway ski trains. I actually called the railway last week to try and get answer - becuase I want to do the same thing your talking about. However, the women I spoke with couldn't give me a straight answer. I asked if they were allowing people to park in their parking lot. (My guess is the actual trailhead is not plowed.) She said yes - but they open at nine and close at 5. I then asked if that meant we could park earleir and pay after climbing - she said she thought so. What about if you come after 5pm - she didn't know. So - I would call them - and do us a favor - let us know how it works out - I am sure many have the same question!!
thanks!!
