So, I visited the entrance to the Rubicon the other day to check on conditions. Yes, I rode my bicycle.
Although there was snow on the paved road, I’m sure access to the staging area is easily doable.
Unfortunately, as I write this, there are chain restrictions on 80, 50 and 431. So, assume there is snow falling on the Rubicon.
Some of the side trails are approaching their opening dates. Please tread lightly as damage can be done.
The current weather system demonstrates that you should be prepared to spend the night every time you go out on the Rubicon: food, shelter, clothing, water, medications, means to stay warm, etc.
Summer is coming, but it’s not here yet.
