Slidebrook generally does not run on Fridays.
It generally does run on Saturdays, but remember that if there isn't enough snow to safely evacuate it, they won't run it. Certainly not a problem at the moment, but don't expect me to second-guess New England weather.
In two weeks, we could all be in our bathing suits or needing snorkels to breathe thru all the powder.
